Infinity Mirror Versus LCD Display
Display and Monitoring
Product B features a 1.6-inch LCD screen with a 400x400 resolution. This display shows real-time system information, such as CPU and GPU temperature and fan speed, alongside custom images and animations. Product A lacks any screen. Instead, it uses an infinity mirror design. This creates a multi-layer optical effect visible from any angle. It emphasizes 40 LEDs in each fan. You get visual flair with Product A, but Product B offers functional data monitoring directly on the fan. Choose Product B if you want to read hardware stats without opening software.
Connectivity and Control
Product B uses 2.4 GHz wireless control to manage RGB lighting and the LCD screen. It requires a separate wireless controller unless you own a compatible Lian Li controller. Product A uses wired connections. The triple pack includes a controller that supports up to 16 fans across four groups. It also supports two SM-type connecting devices. Product A provides a complete wired solution out of the box. Product B requires you to purchase a controller separately if you do not have one. Product A is simpler for wired builds, while Product B offers wireless flexibility.
Lighting Effects
Both fans contain 40 LEDs per unit. Product A allows you to customize the fan blades and the inner frame edges individually. You can choose preset combined lighting effects or set custom modes. Product B also offers 40 LEDs with various RGB effects. However, Product B integrates these lights with the LCD screen content. The software lets you upload MP4, GIF, JPG, or PNG files to the screen. Product A focuses on pure light patterns. Product B combines lighting with visual media. Both provide extensive customization options for your case aesthetics.
Physical Dimensions
Both fans share a 120mm size. Product A measures 2.7 inches in height. Product B is taller at 6 inches due to the LCD module. Product A weighs 15.9 ounces for the triple pack. Product B weighs less individually but includes the wireless module. The height difference matters for clearance. Product A fits standard radiator slots easily. Product B requires more vertical space. Check your case dimensions carefully. If you have limited clearance, Product A is the safer choice. If you have ample space, Product B fits without issues.
Radiator Compatibility
Product A features a removable keylock and a reversible cable module. This design improves compatibility with radiator fittings. It allows for easier installation in tight spaces near water cooling lines. Product B uses a slide-in daisy-chaining mechanism. It secures fans firmly but does not mention a reversible cable module. The wireless nature of Product B removes cable clutter, which can help with radiator clearance. However, Product A explicitly addresses radiator fitting interference. If you use dense radiators, Product A offers specific mechanical advantages.
Choose Your Preferred Display Style
Users wanting real-time system monitoring
Product B includes a 1.6-inch LCD screen with 400x400 resolution. You can view CPU and GPU temperatures directly on the fan. It also supports custom GIFs and JPGs. This hardware dashboard replaces the need to open software separately. The wireless controller manages these data streams without extra cables.
Users preferring simple aesthetic lighting
Product A focuses on visual clarity with its infinity mirror design. The 40 LEDs per fan create a multi-layer effect visible from any angle. It lacks a screen, keeping the surface smooth. The included controller supports up to 16 fans. You get customizable lighting modes without the complexity of a display interface.
Users building a wireless setup
Product B uses 2.4 GHz wireless control for RGB and LCD functions. You do not need a dedicated data cable for each fan. The interlocking system still manages power connections neatly. Note that a separate controller is required for the single pack. This wireless approach simplifies cable routing in tight spaces.

Frequently asked questions
Do both fans use the same mounting holes?
Yes. Both the Lian Li UNI Fan SL-Infinity and the SL LCD Wireless share a 120mm size. This standard form factor allows you to install either model in typical PC case fan mounts or radiator slots without needing special adapters. You can mix them if your case supports varied airflow patterns.
Which fan is better for strict cable management?
The SL-Infinity Triple Pack is better for tidy builds. It uses Lian Li’s interlocking cable management system to connect multiple fans in a chain. This reduces the number of individual cables running to your motherboard. The SL LCD Wireless requires a compatible controller for its wireless operation, which may add more clutter.
Can I see system stats on the SL-Infinity?
No. The SL-Infinity model lacks any display hardware. It focuses on consistent lighting effects across a multi-fan setup. If you need to monitor CPU or GPU temperatures directly on the hardware, you must choose the SL LCD Wireless, which features a dedicated screen for real-time data visualization.
Does the LCD fan work without a controller?
No. The SL LCD Wireless requires a compatible controller to function. It is designed as a visual monitoring tool for users who already own the necessary hardware. Without this controller, the wireless features and screen display will not operate. The SL-Infinity uses wired connections for direct control.
What is the difference in physical dimensions?
Both fans share a 2-inch width, but their heights differ. The SL-Infinity measures 2.7 inches in height. The SL LCD Wireless measures 6 inches in height. This difference affects how much space each fan occupies in your case. You should check your clearance before installing the taller LCD model.
Is the SL-Infinity sold as a single unit?
No. The top-ranked product is the Lian Li UNI Fan SL-Infinity Triple Pack. It comes with three 120mm fans bundled together. This is ideal for builders who want consistent lighting across multiple slots. The SL LCD Wireless is listed as a single 120mm unit.
Which fan supports custom images on its display?
Only the SL LCD Wireless supports custom visuals. Its 1.6-inch LCD screen allows you to upload custom GIFs and JPGs. The SL-Infinity does not have a screen, so it cannot display custom images. It relies on LED lighting patterns for visual customization instead.
