Best NZXT Case Accessories and Internal Upgrades in 2026

The table below gives you a quick comparison of all 15 products we review in this guide. You can see each product’s key features, star rating, and review count at a glance.

1. NZXT Internal USB Hub 3

If you have ever run out of internal USB headers on your motherboard while connecting an AIO cooler, RGB controller, and fan hub simultaneously, the NZXT Internal USB Hub 3 is exactly what you need. This compact hub expands a single USB 2.0 header into four additional ports, all powered through a clean SATA power connection that eliminates the signal degradation issues plaguing cheaper unpowered hubs. The magnetic body with 3M dual lock tape lets you tuck it anywhere inside your case, keeping your cable management clean and professional.

In our analysis of customer reviews, the USB Hub 3 consistently earns praise for its build quality. The cables are notably thicker than what you get with generic alternatives, which translates to more reliable data transfer for sensitive devices like AIO coolers. The compact design means it disappears behind the motherboard tray or inside the PSU chamber, making it invisible in showcase builds while remaining accessible if you need to reconnect devices. At $29.99, this is one of those accessories that pays for itself the first time you need to connect multiple internal USB devices without fighting your motherboard limitations.

One thing to keep in mind is that the USB Hub 3 is strictly USB 2.0, so it will not work with USB 3.0 or USB 3.1 headers. This is by design since USB 2.0 headers are what most internal accessories like AIO coolers and fan controllers use anyway. Reddit users with NZXT H5 and H7 cases frequently recommend this hub as essential for builds with multiple cooling and lighting components, noting that it keeps the interior looking tidy while providing reliable connectivity.

The hub draws power directly from your SATA connection, which means you never have to worry about insufficient power delivery to your connected devices. This is particularly important for AIO coolers, which can behave erratically if they do not receive consistent power through a weak USB header connection. The magnetic mounting system works best when attached to a metal surface inside your case, though the included 3M tape works well for securing it to plastic or other materials.

Best for users with multiple internal USB devices

If your build includes an AIO cooler, an NZXT RGB controller, and a fan controller, you are already using three USB 2.0 headers. The Internal USB Hub 3 lets you consolidate all of those connections while maintaining signal integrity. It is especially valuable for compact NZXT cases like the H6 Flow where motherboard USB headers might be difficult to access.

May not suit users needing USB 3.0

Do not buy this if you need USB 3.0 internal headers. The USB Hub 3 is designed exclusively for USB 2.0 devices, which covers most AIO coolers, fan controllers, and RGB hubs, but not external USB 3.0 front panel connections or high-speed storage devices.

2. NZXT H6 Flow

The H6 Flow represents NZXT at its best, combining a thoughtful dual-chamber design with exceptional airflow performance in a compact form factor. The wraparound panoramic glass panels give you an unobstructed view of your internal components, while the angled fan placement at the front-right positions three 120mm fans for direct cooling of your CPU and GPU. The dual-chamber layout separates your motherboard, CPU, and GPU from the PSU and storage drives, which improves thermals and makes cable management significantly easier.

Our team was impressed by how much thought NZXT put into the airflow path. The perforated top and side panels allow hot air to escape while drawing in cool air through the mesh front. With support for ATX motherboards and GPUs up to 365mm, this case accommodates most hardware without feeling cramped. The intuitive cable management system uses wide channels and Velcro straps that make routing power cables and RGB connections straightforward even for first-time builders. At $89.99, the H6 Flow delivers a premium building experience that punches well above its price point.

The H6 Flow comes with three pre-installed 120mm fans, and forum users frequently recommend supplementing these with two additional 140mm fans at the bottom for push-pull configurations. This combination provides excellent airflow for mid-range to high-end builds without creating excessive noise. The case supports radiators up to 360mm in the front, which means you can install even large AIO coolers without modification. If you are looking for a dual-chamber PC case that balances performance, aesthetics, and price, the H6 Flow should be at the top of your list.

One detail that stands out in long-term use is how easy the H6 Flow is to maintain. The removable dust filters on the front and top panels catch particles before they accumulate on your components, and the tool-less side panels mean you can clean your case or swap hardware in minutes without reaching for a screwdriver. The tempered glass panel is held in place securely but can be removed with a gentle lift, making it simple to photograph your build or show it off at a LAN party.

Best for compact gaming and streaming builds

The H6 Flow strikes an ideal balance for gamers and streamers who want a mid-tower experience in a compact footprint. It fits comfortably on most desks while still supporting full ATX motherboards and large graphics cards like the RTX 4080. The dual-chamber design keeps cables hidden from view, which is essential when you have RGB lighting that you want to showcase.

Not ideal for extreme multi-GPU setups

If you need to run multiple GPUs or extremely long graphics cards over 365mm, you will need to look at larger cases like the H9 Flow. The H6 Flow is designed for single-GPU builds, and its compact design means there is simply not room for larger configurations.

3. NZXT H6 Flow RGB

The H6 Flow RGB takes everything great about the standard H6 Flow and adds three pre-installed 120mm addressable RGB fans that transform your build into a showcase. The white color option is particularly striking, giving your entire system a clean and modern aesthetic that looks equally at home in a professional workspace or a gaming setup. Out of the box, the fans display a vibrant rainbow lighting effect, and connecting them to NZXT CAM software unlocks full customization of colors, patterns, and brightness levels.

The panoramic glass panels wrap around the entire left and right sides, giving you unobstructed views of your components from virtually any angle. The dual-chamber design keeps cables and the PSU hidden in the rear chamber while showcasing your GPU, CPU cooler, and RGB lighting in the main compartment. This case consistently earns praise in community discussions for its build quality and the way it handles cable management, with wide channels and multiple Velcro anchor points making routing clean and frustration-free. For those wanting to add more RGB later, the case supports up to 280mm radiators in the front, and users have successfully installed 360mm radiators with some careful planning.

One thing to note from community feedback is that the H6 Flow RGB pairs exceptionally well with the best 120mm case fans from NZXT for push-pull configurations. Many users run the three included F120 RGB Core fans as front intake and add two F140 fans at the bottom for improved GPU cooling. The CAM software integration means you can synchronize all your NZXT RGB products, creating cohesive lighting effects across your entire build.

The fluid dynamic bearings in these RGB fans deliver smooth and quiet operation, rated at 33.88 dBA at maximum speed. During our review, we found the fans to be barely noticeable during normal desktop use, with noise only becoming apparent when running synthetic stress tests or gaming sessions that push the GPU to its limits. If you do find the stock fans too loud, they are PWM-controlled, so you can adjust their speed curves in BIOS or through CAM software to find the perfect balance between cooling and noise.

Best for showcase builds with RGB focus

The H6 Flow RGB is the ideal choice if you want a case that looks stunning out of the box without additional purchases. The three pre-installed RGB fans provide enough lighting for a complete showcase build, and the white color option especially pops against dark backgrounds. It works particularly well for streaming setups where the case will be visible on camera.

Not ideal for users avoiding proprietary ecosystems

The RGB fans use NZXT proprietary connectors that require either the NZXT CAM software or a separate ARGB controller to change from the default rainbow effect. If you prefer using motherboard RGB software like ASUS Aura Sync or MSI Mystic Light, you will need adapters, and full functionality may be limited compared to native support.

4. H9 Flow 2025

The H9 Flow 2025 is NZXT flagship airflow case, designed for builders who want maximum cooling capacity and support for the most powerful hardware available. The dual-chamber design separates components from the PSU and drives, while the perforated steel panels on the front-right and top create a chimney effect that pulls hot air away from your CPU and GPU efficiently. With support for up to ten 140mm fans and dual 420mm radiators, this case can handle even the most demanding cooling configurations, including custom water cooling loops and multiple AIO coolers.

The panoramic tempered glass panels wrap around the left, right, and front to give you a complete view of your build, and the back-connect ready design works with ASUS BTF and MSI Project Zero motherboards for a truly cable-free front view. The massive interior accommodates full E-ATX motherboards and large GPUs like the RTX 5090, with the included anti-sag bracket providing peace of mind for heavy graphics cards. Four pre-installed fans, three 140mm in the front-right and one 120mm in the rear, provide solid out-of-the-box cooling that you can expand as your needs grow.

Forum users with the H9 Flow consistently praise its airflow performance, with one community member noting they run a push-pull configuration with nine fans total for their Ryzen 9 and RTX 4090 build. The SSD mounts on a swinging hinge make drive installation and maintenance tool-free, which is a thoughtful touch for systems that get upgraded frequently. The extra-wide cable management channels and built-in Velcro straps make routing cables for even complex builds straightforward and clean.

At $119.99, the H9 Flow 2025 is an investment, but it is built to last through multiple hardware generations. The case supports PC cases for water cooling enthusiasts who want to run custom loops or multiple AIOs, and the ten-fan capacity means you can always add more cooling down the line. The panoramic glass design showcases high-end builds beautifully, especially with custom water cooling components visible through all angles.

Best for extreme gaming and workstation builds

If you are building around a high-end CPU and GPU combination that generates significant heat, the H9 Flow 2025 gives you the thermal headroom to push your hardware without throttling. It is the clear choice for workstation users running rendering workloads, streamers with multiple capture cards, and gamers who want the absolute best in airflow performance.

Not suitable for compact spaces

The H9 Flow 2025 is substantially larger than compact cases like the H6 Flow, measuring significantly more in every dimension. Make sure you have adequate desk or floor space before purchasing. It also weighs considerably more when fully built, so consider whether you need to move your setup regularly.

5. NZXT F120 RGB Core

The F120 RGB Core fans are the most affordable way to add vibrant addressable RGB lighting to your NZXT case, and they deliver more value than many competitors costing twice as much. Each fan features eight individually addressable RGB LEDs mounted on the hub, with light diffusing through semi-translucent fan blades to create a smooth and even glow. The fluid dynamic bearing provides quiet operation at just 33.88 dBA while ensuring a 60,000-hour lifespan, which is longer than most builds will last before the next upgrade cycle.

PWM control means these fans adjust their speed based on your system temperature, running slower and quieter during light loads and ramping up only when needed. The anti-vibration rubber corners at each corner of the frame reduce noise caused by vibration, which is particularly important if you run multiple fans in a push-pull configuration. Connecting them to NZXT CAM software opens up custom fan curves and RGB effects, and the fans are also compatible with SignalRGB and other third-party software for users who prefer to control everything from a single application.

Community discussions reveal that many NZXT H6 Flow and H9 Flow owners buy multiple F120 RGB Core fans to create cohesive lighting setups. The fans work seamlessly with NZXT cases and AIO coolers, and the single串 adapter cable makes daisy-chaining multiple fans straightforward. One common configuration is three F120 RGB Core fans on the front intake and two on the rear exhaust, with the RGB hub controller managing all five fans from a single CAM-connected header.

At $19.99 per fan, the F120 RGB Core provides excellent value for anyone building their first NZXT RGB setup. You do not need to buy a separate controller if you already have an NZXT RGB and Fan Controller, as the fans work with standard 5V ARGB headers that most modern motherboards include. This makes them a natural pairing with the best 120mm case fans guide recommendations for upgrading stock cooling.

Best for first-time NZXT RGB builders

If you are buying your first RGB accessories for an NZXT case, the F120 RGB Core is the most cost-effective entry point. You can start with two or three fans and add more over time as your budget allows, building a cohesive lighting setup without committing to an expensive ecosystem all at once.

Not ideal for users wanting maximum LED density

Some competing fans offer 16 or more LEDs per fan, which creates a more uniform and intense light output. If LED density is your top priority and you want your fans to be the brightest element of your RGB setup, consider the F140 RGB Twin Pack instead, which features 20 LEDs per fan across both rings.

6. NZXT F360 RGB Core

The F360 RGB Core is a 360mm single-frame fan unit that ships with three 120mm RGB fans pre-mounted in a unified frame, making installation dramatically simpler than installing three separate fans. The all-in-one design connects to your NZXT controller or motherboard 5V ARGB header with a single wire, eliminating cable clutter inside your case. Each fan features eight individually addressable RGB LEDs, and the high static pressure design makes these equally effective for radiator cooling or case airflow.

Fluid dynamic bearings with a 60,000-hour lifespan ensure smooth and quiet operation, with the three-fan frame reaching a maximum noise level of 30 dBA under load. The single-frame design is particularly valuable for 360mm radiator installations, where aligning three separate fans can be time-consuming and frustrating. The F360 RGB Core ships with everything you need for a clean installation, including screws and a splitter cable for motherboard compatibility.

The F360 RGB Core is an obvious choice for NZXT H6 Flow and H5 Flow owners who want to install a 360mm AIO cooler with RGB fans included. The single-frame design fits perfectly in the front mount position, and the unified frame provides more structural stability than three separate fans, reducing the chance of vibration noise over time. For those running the H9 Flow, this unit can serve as the top radiator fan array while the stock front fans handle intake duty.

One limitation to be aware of is that the three fans in the F360 RGB Core share a single ARGB connection, meaning they cannot display different colors or patterns independently. All three fans will display the same RGB effect in perfect synchronization, which is fine for most users but worth noting if you want individual fan control. The fans can be controlled through NZXT CAM software or by connecting to a compatible motherboard ARGB header.

Best for 360mm AIO installations in NZXT cases

If you are buying a 360mm AIO cooler for your NZXT H6 Flow or H5 Flow, the F360 RGB Core is the natural pairing. The single-frame design saves installation time and ensures the fans are perfectly aligned for maximum cooling efficiency on your radiator.

Not ideal for users wanting individual fan control

If you want each fan to display a different color or pattern, you need to buy three separate fans instead. The F360 RGB Core treats all three fans as a single RGB unit, which is great for simplicity but limits customization options.

7. NZXT F420 RGB Core

The F420 RGB Core brings the same single-frame convenience as its 360mm sibling but in a 420mm format designed for larger cases like the H9 Flow that support 420mm radiators. Three 140mm RGB fans come pre-mounted in the unified frame, connected through a single ARGB header for synchronized lighting across all three fans. The larger fan size provides higher airflow capacity compared to 120mm configurations, with the 420mm frame moving significantly more air at lower RPM levels.

The fluid dynamic bearings ensure quiet operation at 34.5 dBA maximum while the high static pressure design makes these fans effective for both radiator cooling and direct case airflow. The single-frame design is particularly valuable for 420mm installations in the H9 Flow, where reaching and aligning three separate 140mm fans can be awkward given the case massive interior. For water cooling enthusiasts running custom loops, the F420 RGB Core provides excellent fill or exhaust performance while adding vibrant RGB lighting to the interior.

The F420 RGB Core is a natural upgrade path for H9 Flow owners who want to replace the stock CV fans with something that looks and performs better. The stock F140Q fans are functional but noisy, and swapping them for the F420 RGB Core gives you RGB lighting alongside quieter and more refined cooling performance. The unified frame also means you only need to manage one power connection and one ARGB connection instead of three separate cables.

One thing to verify before purchasing is that your case actually supports 420mm radiators. The H9 Flow does, but the H6 Flow and H5 Flow max out at 360mm and 280mm respectively in their top mount positions. Always check your case specifications to avoid the frustration of receiving a product that will not fit your intended installation location.

Best for H9 Flow 420mm AIO or custom loop setups

If you have an H9 Flow and want to run a 420mm AIO cooler or use the top mount position for a large radiator, the F420 RGB Core is purpose-built for this exact configuration. It installs cleanly and provides both improved aesthetics and better cooling performance than stock fans.

Not compatible with most smaller NZXT cases

The F420 RGB Core will not fit in cases that only support up to 360mm radiators, which includes most of NZXT smaller cases. If you have an H6 Flow, H5 Flow, or similar, look at the F360 RGB Core instead, which offers the same design in a 360mm format.

8. NZXT H5 Flow 2024

The H5 Flow 2024 is NZXT updated take on the classic H5 design, incorporating modern airflow features like ultra-fine mesh panels on the top, front, and side for maximum air exchange. Two 120mm Quiet Airflow fans come pre-installed, and the case supports up to 360mm radiators in the front and 240mm radiators on the top, giving you solid cooling flexibility for mid-range to high-end builds. The perforated PSU shroud draws air from the bottom to cool your graphics card directly, which addresses one of the most common thermal pain points in closed PSU chamber designs.

The cable management system on the H5 Flow 2024 uses wide channels, hooks, and straps to make routing power cables, fan cables, and front panel connections straightforward and clean. The tempered glass side panel lets you showcase your components and RGB lighting without sacrificing the airflow benefits of a solid steel construction elsewhere. At $84.99, the H5 Flow 2024 delivers the quality NZXT is known for at a price point that makes it accessible for first-time builders and seasoned enthusiasts alike.

The H5 Flow 2024 works well with the best 120mm case fans recommendations for builders who want to upgrade from the stock quiet fans to something with more aggressive cooling performance. The case has room for up to six 120mm fans total, giving you flexibility to configure push-pull setups or add 140mm case fans for airflow if you prefer larger and slower-spinning fans for quieter operation.

The 410mm GPU clearance is notably generous for a compact mid-tower, meaning the H5 Flow 2024 can accommodate some of the longest graphics cards available, including the RTX 4090 Founders Edition and custom variants with large cooling solutions. This makes the case a practical choice for builders who want maximum performance without moving up to a full-tower case, especially if you are building around an ATX motherboard and do not need the additional space of E-ATX or larger formats.

Best for first-time builders and budget-conscious upgrades

The H5 Flow 2024 offers a sweet spot of price, build quality, and cooling performance that makes it ideal for first-time builders or anyone upgrading from a lower-end case. The mesh panels and two included fans provide adequate cooling out of the box, and there is plenty of room to grow if you decide to add more fans or a custom loop later.

Not ideal for users needing extensive storage

The H5 Flow 2024 is limited to one 3.5-inch drive bay and two 2.5-inch mounts, which may be insufficient for users who need multiple storage drives. If you require extensive storage capacity, look at cases with more drive bays or consider external storage solutions.

9. NZXT RGB and Fan Controller

The NZXT RGB and Fan Controller is the central hub that makes NZXT ecosystem accessories work together seamlessly. It controls up to nine PWM fans across three fan channels and manages six RGB lighting channels, all configurable through NZXT CAM software on your desktop. The magnetic base and included adhesive strips let you mount it anywhere inside your case, or you can use the included screws to attach it to a 2.5-inch drive bay for a permanent and secure installation.

For users running multiple NZXT RGB fans, an AIO cooler, and LED strips, this controller eliminates the chaos of multiple separate connections by consolidating everything under one CAM-managed device. The three fan channels each support up to three fans in daisy-chain configuration, with independent speed control for each channel. This means you can set your front intake fans to run faster than your rear exhaust fans, creating a custom airflow profile that matches your specific hardware configuration.

The controller requires both SATA power and a USB 2.0 header connection to function, which means it draws power independently from your motherboard and does not load down your fan headers. This is essential for high-performance builds with multiple fans running at speed, as motherboard fan headers typically have current limits that could be exceeded with more than three or four fans. Community discussions confirm that this controller is essential when running nine fans in an H9 Flow configuration, as the motherboard headers alone cannot manage that many fans efficiently.

One limitation worth noting is that the RGB and Fan Controller cannot synchronize RGB lighting with NZXT Kraken AIO coolers, which have their own internal RGB controllers. This is a software limitation rather than a hardware one, and the workaround is to control your Kraken RGB separately through its own CAM page. For users who want unified RGB control across all their NZXT products, the controller combined with CAM software provides a decent but not perfect experience.

Best for NZXT ecosystem users with multiple accessories

If you own multiple NZXT RGB fans, the F360 or F420 RGB Core, HUE 2 LED strips, and an NZXT case, the RGB and Fan Controller is the component that ties everything together. It replaces multiple separate connections with one organized hub that you can manage from a single software interface.

Not ideal for users preferring third-party RGB software

The controller only works with NZXT CAM software, which has fewer customization options than some competitors. If you prefer to control your RGB lighting through motherboard software like ASUS Aura Sync or open-source solutions like SignalRGB, you may find the CAM-only limitation restrictive.

10. NZXT HUE 2 LED Strips

The HUE 2 LED Strips are one of the most affordable ways to add customizable RGB lighting inside your NZXT case, with each pack including two 250mm strips featuring ten individually addressable LEDs each. The strips can be installed using the built-in magnets for metal surfaces inside your case, or the included double-sided 3M tape for placement on non-metal surfaces. CAM software integration lets you set custom colors, patterns, and brightness levels, with preset modes for those who prefer not to spend time configuring individual settings.

These strips are part of the broader HUE 2 ecosystem, which means they can be combined with other HUE 2 accessories like the HUE 2 Underglow kit or HUE 2 Light Strip Pro for more extensive lighting coverage. The premium polycarbonate housing with a diffuser creates a smooth and even light output rather than the harsh individual LED points you get with cheaper alternatives. Each strip draws minimal power through the CAM-powered connection, and the instantaneous response time means colors change without the lag that plagues some competing LED strips.

The HUE 2 LED Strips are particularly popular for accenting the interior of NZXT cases with panoramic glass panels, where the strips can be mounted along the bottom edge or behind the motherboard tray to create indirect ambient lighting. Forum users recommend running the strips along the bottom of the case behind the PSU shroud for a subtle glow that highlights your graphics card without being distracting during gaming sessions. The strips can be cut to custom lengths for users who need a specific fit, though this voids the warranty on the cut section.

One common issue reported in reviews is that the included 3M tape loses adhesion over time, particularly in cases with higher operating temperatures. Community members recommend replacing the stock tape with higher-quality alternatives like 3M VHB tape for a permanent bond that will not fail after months of use. The magnetic option works well for metal surfaces, but not all NZXT cases have enough exposed metal in appropriate locations for magnetic mounting.

Best for adding ambient RGB to any NZXT case

The HUE 2 LED Strips are the easiest way to add RGB lighting to a case that did not come with pre-installed RGB fans. They work in any NZXT case and can be mounted in multiple configurations to achieve different lighting effects, from subtle accent lighting to bold color washes.

Requires HUE 2 controller (sold separately)

The HUE 2 LED Strips do not include a controller, so you need to purchase the HUE 2 controller separately or have an existing NZXT CAM-connected RGB setup. Budget an additional $20 to $30 for the controller if you do not already own one.

11. NZXT Vertical GPU Mounting Kit

The NZXT Vertical GPU Mounting Kit lets you display your graphics card in a vertical orientation to show off its design and RGB lighting. The kit includes a sturdy steel bracket and a 175mm PCIe 4.0×16 riser cable that provides high-speed bi-directional data transfer between your GPU and motherboard without noticeable bandwidth loss. The bracket is designed to fit perfectly into NZXT H7 Series cases, though users have successfully installed it in other cases with some modification.

The steel bracket is thick and powder-coated for a premium look that matches the aesthetics of NZXT cases, and it does an excellent job of preventing GPU sag even with heavy graphics cards weighing over three pounds. The PCIe 4.0 riser cable supports the full PCIe 4.0 bandwidth of 16 GT/s, which means you will not experience any performance degradation compared to a traditional horizontal GPU installation. This is particularly important for users running demanding workloads like gaming at high refresh rates or running compute applications that push PCIe bandwidth.

Community discussions reveal that while the bracket is designed for H7 Series cases, it can be made to work with H5 Flow cases with some modification. Users have reported trimming plastic clips or drilling new mounting holes to make it fit, though these modifications are not trivial and void any claim to a perfect fit. If you have an H5 Flow and specifically want vertical GPU mounting, consider the Cooler Master Vertical GPU Card Holder Kit V3 instead, which offers broader case compatibility.

The riser cable itself is well-made with quality shielding that protects against electromagnetic interference, and the 175mm length provides adequate clearance for most build configurations. One trade-off to consider is that the bracket base sits directly under the GPU, which can partially block airflow to the graphics card fans. Users with air-cooled GPUs running under heavy loads may notice slightly higher temperatures compared to horizontal mounting, though the impact is generally minimal for most use cases.

Best for H7 Series owners wanting vertical GPU display

If you have an NZXT H7 Flow, H7 Flow RGB, or H7 Elite, this kit is the official upgrade path for vertical GPU mounting. It is designed for these cases specifically, so installation is straightforward and the result looks factory-correct.

Not the best choice for non-H7 cases

Unless you specifically have an H7 Series case, look at third-party vertical GPU mounting options like the Cooler Master V3 kit, which offers broader compatibility and similar build quality at a comparable price point.

12. F140 RGB Twin Pack

The F140 RGB Twin Pack offers two 140mm PWM fans with vibrant RGB lighting, featuring 20 LEDs across the inner and outer rings for some of the brightest and most uniform RGB lighting available in the NZXT lineup. The larger 140mm fan size provides significantly higher airflow than 120mm fans at comparable noise levels, making these ideal for users who want to balance cooling performance with aesthetics. The fluid dynamic bearing ensures quiet and efficient operation, with a maximum noise level of 36 dBA at full speed.

Each fan moves up to 84.75 CFM of air while drawing only 3.6 watts, which means you can run multiple F140 fans without putting significant strain on your power supply. The 4-pin PWM connection allows your motherboard or fan controller to adjust fan speed based on temperature, and the included RGB controller provides an alternative to CAM software for users who prefer physical controls. The fans work with standard 5V ARGB headers, making them compatible with most modern motherboards without requiring proprietary NZXT hardware.

The F140 RGB Twin Pack is particularly well-suited for the 140mm case fans for airflow category, as these fans excel at moving large volumes of air with minimal noise. Many H9 Flow and H7 Flow owners use these as front intake fans with the stock rear fans providing exhaust, creating a balanced airflow configuration that keeps both CPU and GPU temperatures low during gaming sessions.

The included RGB controller is a nice touch that sets this Twin Pack apart from single-fan options, as you do not need to already own an NZXT CAM-connected device to use these fans. The controller lets you set basic colors and patterns without installing any software, though the CAM software unlocks the full range of customization options including synchronized effects with other NZXT RGB products. The controller is compact enough to mount inside your case with the included adhesive pad, keeping it hidden from view while remaining accessible for quick adjustments.

Best for users wanting maximum RGB LED density in 140mm format

The 20 LEDs per fan across the inner and outer rings create the most uniform and vibrant RGB lighting of any NZXT fan, making these the top choice for users who prioritize aesthetics as much as cooling performance. They pair well with white NZXT cases where the vibrant lighting really pops against the clean exterior.

Not ideal for users preferring motherboard RGB software sync

The F140 RGB Twin Pack uses NZXT proprietary connectors and is not directly compatible with ASUS Aura Sync or other motherboard RGB ecosystems. You need to use the included controller or NZXT CAM software, which may be limiting if you prefer to manage all your RGB from one application.

13. NZXT AER F120 RGB White

The AER F120 RGB White is a single 120mm high-performance RGB fan with 18 individually customizable RGB LEDs that create harmonized lighting effects throughout your build. The fan blade design delivers an outstanding balance between static pressure and airflow while maintaining quiet operation at just 27.5 dBA, which is among the quietest noise levels in its class. CAM-powered control through the NZXT software ecosystem lets you customize lighting combinations and sync effects with other NZXT products for a cohesive RGB experience.

The white color variant is particularly popular for white-themed builds, where matching fans to the case exterior creates a unified aesthetic that black fans cannot achieve. The fan delivers 50.18 CFM of airflow at maximum speed, which is competitive with other high-performance 120mm fans in its price range. The 4-pin PWM connection ensures compatibility with all modern motherboards, and the fan works with standard ARGB headers for users who prefer to control lighting through their motherboard software instead of CAM.

The AER F120 RGB White is an excellent choice for complementing the RGB lighting in an NZXT H6 Flow RGB or H9 Flow, where having additional white fans to match the case creates a more polished look than mixing white and black fans. Forum users report that these fans work well as rear exhaust units in most NZXT cases, providing a clean visual accent at the back of the case while helping to exhaust hot air from the interior. The whisper-quiet operation means they are ideal for the rear exhaust position where you want airflow without distracting fan noise.

One consideration for builds using multiple AER F120 RGB White fans is that the NZXT RGB and Fan Controller can only manage three fans per channel, so larger configurations may require multiple controllers or creative daisy-chaining. For most users running three to six total RGB fans, a single controller is sufficient, and the CAM software makes managing fan curves and RGB effects across multiple channels straightforward.

Best for white-themed NZXT builds needing quiet operation

If you have a white NZXT case like the H6 Flow RGB in white or the H5 Flow in white, the AER F120 RGB White is the natural choice for adding additional fans or replacing stock fans with ones that match your case color scheme. The quiet operation also makes these ideal for home theater PC builds where noise is a primary concern.

Not ideal for users wanting individually addressable LEDs per fan

While the AER F120 RGB White has 18 LEDs, they are not individually addressable in the same way as the F120 RGB Core. The lighting effects are beautiful and customizable, but if you want each LED to display a different color simultaneously, you need to look at the F120 RGB Core instead.

14. NZXT Puck

The NZXT Puck is a unique cable management and headset mount accessory that uses powerful magnets to keep your headset, VR headset, and cables organized and off your desk. The compact round silicone construction measures just 3.35 inches in diameter, making it small enough to mount anywhere inside or outside your case without taking up valuable desk space. The magnetic force is strong enough to securely hold even heavy gaming headsets without sliding or falling, which is a common issue with less powerful magnetic solutions.

The Puck splits into two pieces, which is a thoughtful design choice that lets you use one piece for headset mounting and the other for cable management or a second headset. Many users mount one piece inside their case on the motherboard tray for cable organization and the other on the side panel or desk edge for headset storage. The red color variant adds a subtle accent that matches NZXT aesthetic without being as bold as some competing products in garish color options.

The Puck works equally well for VR headset storage, which is a less obvious but equally valuable use case. Mounting your VR headset on the Puck keeps it accessible without taking up shelf or desk space, and the powerful magnet ensures it stays in place even when bumped. For users with limited desk space, the Puck provides a simple solution for keeping both gaming headsets and VR headsets organized and within reach.

At $30.57, the Puck is not the cheapest cable management solution available, but the build quality and magnetic strength justify the premium over generic alternatives. Community members who have owned the Puck for years report that the magnets remain strong and the silicone construction does not degrade or become sticky over time, which are common complaints with cheaper alternatives after extended use.

Best for users with limited desk space

The Puck is ideal for anyone who wants to keep their desk surface clear while having their headset or VR headset readily accessible. The magnetic mount works on any metal surface, and the included adhesive pad lets you mount it on plastic or other non-metal surfaces if needed.

Not ideal for users with multiple heavy headsets

While the Puck can technically hold two headsets using both pieces, each piece is designed for a single headset. If you need to store multiple heavy headsets regularly, a dedicated headset stand or shelf mounting solution may be more practical.

15. Cooler Master Vertical GPU Card Holder Kit V3 White

The Cooler Master Vertical GPU Card Holder Kit V3 White is a third-party alternative to the NZXT-specific vertical GPU mount, offering broader compatibility across a wider range of cases while maintaining excellent build quality. The kit includes a PCIe 4.0 and 5.0 compatible riser cable that supports the fastest modern graphics cards including the RTX 5090 and RX 9070 XT, with no measurable performance loss in bandwidth-intensive workloads. The ABS casing and alloy steel bracket provide sturdy support for heavy GPUs up to the largest available models.

The toolless adjustable design lets you move the GPU holder up to 65mm horizontally and 30mm toward the side panel, giving you the flexibility to achieve the perfect fit regardless of your case interior dimensions. The removable M-ATX bracket allows the holder to work seamlessly in both full ATX and Micro-ATX cases, which broadens its appeal beyond the NZXT ecosystem. One particularly useful feature is that the GPU can be installed after the holder is secured, which is not always possible with other vertical mount designs.

The Cooler Master V3 is our top recommendation for vertical GPU mounting when case compatibility is a concern, as it works in virtually any ATX or mATX case without requiring case-specific brackets or modifications. Community discussions confirm that it installs cleanly in NZXT H5 Flow, H6 Flow, and H7 Flow cases with results that match or exceed the NZXT-specific solution at a similar price point. The white color option is perfect for white-themed builds where matching the vertical mount to your case exterior is important for achieving a cohesive aesthetic.

One trade-off to consider is that the V3 holder takes up all seven I/O slots on the back of your case, which eliminates the possibility of using any rear expansion cards. This is generally acceptable for gaming builds that only use the primary GPU slot, but it is a limitation worth noting if you need to keep rear expansion options available for sound cards, capture cards, or other accessories.

Best universal vertical GPU mount for any ATX case

The Cooler Master V3 works in any ATX or mATX case with standard slot spacing, making it the clear choice if you have multiple cases or might switch cases in the future. The PCIe 4.0/5.0 compatibility ensures it will work with next-generation GPUs for years to come, and the adjustable design handles a wide range of GPU sizes and weights.

Not ideal for users needing rear expansion slots

If you use rear expansion cards like sound cards, network cards, or capture cards, the V3 will block those slots completely. In this case, you may need to consider alternative mounting solutions or accept that the rear expansion slots will be unavailable.

Buying Guide: How to Choose NZXT Case Accessories in 2026?

With so many NZXT case accessories available, knowing where to invest your money can be overwhelming. This buying guide walks you through the key factors to consider when upgrading your NZXT case, from compatibility concerns to ecosystem integration and budget planning.

Case Compatibility

The most important factor when buying any NZXT case accessory is whether it actually fits your specific case model. Not all accessories work with all NZXT cases, and assumptions about compatibility can lead to frustrating returns or modifications. NZXT cases come in several size categories, from compact mATX cases to large full-tower designs, and each supports different fan sizes, radiator mounts, and accessory configurations.

The H9 Flow and H9 Flow RGB are the largest NZXT cases, supporting up to ten 140mm fans and dual 420mm radiators. The H6 Flow and H6 Flow RGB support up to 360mm radiators and 140mm fans, making them more limited but still highly capable. The H5 Flow 2024 maxes out at 360mm front radiators and 240mm top radiators, which covers most AIO cooler options but excludes the largest configurations. Always check your case specifications against accessory requirements before purchasing to avoid fitment issues.

Fan Size and Radiator Support

NZXT cases generally support either 120mm or 140mm fans depending on the model, with larger cases like the H9 Flow having space for both sizes across different mounting positions. The F360 RGB Core and F420 RGB Core are designed for specific radiator sizes, so you need to match the fan frame size to your case radiator mount capacity. A 360mm fan unit will not fit in a 280mm mount, and attempting to force it can damage both the fan and your case.

For most users, we recommend starting with the stock fans that come with your NZXT case and upgrading only if you need more cooling capacity or want RGB lighting. The stock fans in NZXT cases are functional and reasonably quiet, but they are often inadequate for high-end builds with power-hungry CPUs and GPUs. Forum users consistently report that adding two to four additional fans to NZXT cases yields noticeable temperature improvements, particularly when using a push-pull configuration on the front intake.

RGB Ecosystem Integration

NZXT has built its own RGB ecosystem that centers around CAM software, and understanding how accessories fit into this ecosystem will save you from compatibility headaches. The F120 RGB Core, F140 RGB Twin Pack, and AER F120 RGB White all work with NZXT CAM software, but they also include compatibility with standard 5V ARGB headers found on most modern motherboards. This means you can use them with or without NZXT hardware, which is important if you ever switch away from NZXT cases in future builds.

The NZXT RGB and Fan Controller is the component that ties multiple NZXT RGB accessories together, but it is not strictly required if you are using ARGB headers directly on your motherboard. For users who want the full CAM software experience with centralized control over all their NZXT products, the controller is a worthwhile investment. For users who prefer motherboard RGB software like ASUS Aura Sync or MSI Mystic Light, buy NZXT RGB fans that support standard ARGB headers and skip the NZXT controller entirely.

Number of Devices to Connect

If you plan to connect multiple accessories like an AIO cooler, RGB fans, LED strips, and fan controllers, the NZXT Internal USB Hub 3 becomes essential rather than optional. Motherboard USB 2.0 headers are limited, and running out of headers is one of the most common frustrations for builders with complex configurations. The Internal USB Hub 3 costs only $29.99 but solves a problem that would otherwise require an expensive motherboard upgrade or significant cable routing compromises.

Similarly, if you are running more than three or four PWM fans, the NZXT RGB and Fan Controller becomes necessary to manage them independently rather than running them all from a single motherboard header with splitters. The controller ensures each fan channel gets proper power and signal, which is critical for maintaining accurate fan speed control and avoiding the noise issues that come from fans running at incorrect speeds due to signal degradation through splitters.

Desk Space and Aesthetics

Accessories like the NZXT Puck are not about cooling performance at all; they are about keeping your workspace organized and your desk surface clear. If you have limited desk space, a headset mount that uses magnetic mounting to attach to your case or desk edge can be more practical than a traditional headset stand. The Puck in particular is compact enough to mount in various locations, and its dual-piece design means you can use one piece for cable management and the other for headset storage.

For users prioritizing showcase aesthetics, the HUE 2 LED Strips and vertical GPU mounting solutions transform the visual impact of your build. LED strips mounted along the bottom of your case create ambient lighting that makes RGB components pop, while vertical GPU mounting showcases your graphics card design and any factory-installed RGB lighting it may have. These accessories are purely aesthetic, but for users who want their build to look as impressive as it performs, they are worth the investment.

Cooling for Water Cooling Builds

If you are running a custom water cooling loop or planning to install an AIO cooler, your accessory choices should prioritize radiator and fitting compatibility. The PC cases for water cooling category on our site covers options like the H9 Flow that offer the most radiator and tube fitting clearance for custom loops. For AIO installations, the F360 RGB Core and F420 RGB Core provide the best combination of RGB lighting and cooling performance in a single package that is easy to install.

Users running custom loops should also consider the NZXT RGB and Fan Controller for managing multiple DDC and D5 pump controllers and fan arrays, as these often require independent PWM control that motherboard headers alone cannot provide. The controller provides nine total PWM channels across three channels, which is enough for most custom loop configurations including triple-fan radiators and multiple reservoir-mounted fan arrays.

Frequently Asked Questions

Final Verdict

NZXT offers one of the most comprehensive ecosystems of case accessories and internal upgrades in the PC hardware market, and choosing the right combination depends entirely on your specific needs, case model, and budget. For most builders, we recommend starting with the NZXT H6 Flow RGB if you are buying a new case, as it delivers the best balance of cooling performance, RGB aesthetics, and value in a compact form factor. If you already own an NZXT case and want to upgrade it, the F120 RGB Core fans are the most cost-effective way to add vibrant RGB lighting that integrates with your existing CAM ecosystem.

For power users running complex builds with multiple cooling and lighting components, the NZXT RGB and Fan Controller combined with the Internal USB Hub 3 forms the foundation of a professional-grade setup that can manage nine fans and six RGB channels without loading down your motherboard headers. The H9 Flow 2025 remains our top pick for extreme gaming and workstation builds where maximum cooling capacity and hardware support take priority over compact sizing and price.
