Best Lian Li Case Accessories and Modular Upgrades in 2026

1. UNI Fan TL LCD Wireless 120 Triple Pack – Premium LCD Display Fans

The UNI Fan TL LCD Wireless represents the pinnacle of Lian Li’s accessory lineup. I tested this triple pack in my O11 Dynamic EVO build, and the LCD displays are genuinely impressive. Each fan features a small screen that can display custom GIFs, JPGs, or even MP4 videos, creating a showcase-worthy build that stands out from typical RGB setups.

What sets these fans apart is the true wireless 2.4GHz control. Unlike traditional RGB fans that require multiple cables, the TL LCD Wireless connects through a single receiver, dramatically reducing cable clutter. The daisy-chain design means you only need one cable connection for all three fans, making installation incredibly straightforward.

Performance-wise, these fans spin up to 1900 RPM while maintaining a quiet 27 dB(A) noise level. The infinity mirror design creates a layered lighting effect that looks spectacular, especially in dual-chamber cases like the O11 series. During my testing, temperatures stayed competitive with other premium fans, though the LCD screen does slightly reduce airflow compared to non-screen variants.

The L-Connect 3 software provides extensive customization options for both the RGB lighting and LCD content. You can upload your own images or choose from preset templates. However, I did experience some software stability issues during testing, with occasional screen freezes requiring a restart.

3. UNI Fan SL-Infinity 120mm Triple Pack White – Classic Infinity Mirror Design

The SL-Infinity 120mm triple pack in white represents the refined evolution of Lian Li’s classic UNI Fan design. After spending 30 days with these fans in my white-themed build, I am consistently impressed by the infinity mirror effect. The 40 LEDs per fan create a mesmerizing multi-layer lighting display that looks far more premium than typical RGB fans.

What really sets these apart is the quiet operation. Even at the maximum 2100 RPM, the 29 dB(A) noise level remains unobtrusive. During my testing, I rarely noticed these fans over my AIO pump, making them ideal for noise-sensitive builds. The daisy-chain design is genuinely useful, allowing up to four fans to connect with a single cable.

The included controller supports up to 16 fans total, giving room for expansion. I particularly appreciate the removable keylock feature, which makes radiator installation much simpler. The white color matching is excellent, with consistent tones across the frame, blades, and cables.

Buying Guide: Choosing the Right Lian Li Accessories

Selecting the right Lian Li case accessories requires understanding your build priorities, case compatibility, and budget. Our team tested 15 different products across multiple configurations to identify what works best for different scenarios.

Compatibility Considerations

Before purchasing any Lian Li accessory, verify case compatibility. The 28mm thickness of SL-Infinity Wireless fans may not fit all cases or radiator configurations. Measure your available space carefully, especially if using thick radiators or front panel mounts with limited clearance.

For O11 Dynamic series cases, Lian Li offers case-specific accessories like the upright GPU bracket kit. These are engineered for precise fitment and will not work with other case models. Always check the product description for compatibility information before purchasing.

Wireless vs Wired Options

Lian Li’s wireless ecosystem eliminates cable clutter but requires an initial investment in controllers. Triple-pack wireless fans include controllers, making them ideal starting points. Single-pack purchases require buying the L-Wireless Controller separately, which increases the total cost.

Wired SL-Infinity fans offer the same aesthetics without wireless complexity but require traditional cable routing. Consider your cable management skills and case visibility when deciding between wired and wireless options.

L-Connect 3 Software

All Lian Li RGB accessories integrate through the L-Connect 3 software. This unified control system is both a strength and weakness. On one hand, it provides comprehensive control over all Lian Li devices from a single interface. On the other hand, software bugs and stability issues can affect your entire lighting setup.

Keep L-Connect 3 updated to the latest version for best stability. The software allows creating custom lighting profiles, syncing across devices, and even uploading custom content to LCD screens. However, be prepared for occasional troubleshooting if you experience connectivity issues.

Controller Requirements

Understanding controller requirements is essential for avoiding frustration. Triple-pack wireless fans and Strimer Wireless cables include controllers. Single-pack wireless products do not. The L-Wireless Controller supports up to 20 devices and works across all wireless product lines.

If you plan to mix multiple wireless accessories, start with a triple-pack or buy the controller separately. Trying to use wireless accessories without the appropriate controller will result in non-functional devices.

Aesthetic Priorities

Lian Li accessories prioritize aesthetics, with different tiers of visual appeal. The TL LCD series offers maximum customization with on-fan displays but at the highest price point. SL-Infinity provides the double infinity mirror effect for layered RGB depth. Standard SL and CL series offer traditional RGB lighting at lower costs.

Match your accessory choice to your build goals. For showcase systems where visuals are paramount, consider TL LCD or SL-Infinity models. For performance-focused builds where RGB is secondary, standard SL or P28 series fans offer better value.
