This article covers Lian Li UNI FAN SL INFINITY 120 ホワイト 3Pack.

Overview

The Lian Li UNI FAN SL INFINITY 120 White 3Pack is a set of three 120mm case fans designed to balance airflow and illumination in modern PC builds. With a maximum speed of 2100 RPM and a noise level of just 29 dBA, these fans deliver effective cooling while remaining quiet. The white housing helps create a clean, unified look inside the chassis. Its standout feature is the modular daisy-chain mechanism, which allows up to four fans to be connected without screws, drastically reducing cable clutter. The infinity mirror design on the center hub and inner frame edges creates a layered LED lighting effect that stands out in any build. Positioned in the mid-to-high-end segment, this kit is ideal for builders who prioritize aesthetics and cable management.

Compatibility Guide

These are standard 120mm x 25mm fans, compatible with most ATX, Micro-ATX, and Mini-ITX cases. They fit standard radiator mounts and case fan slots without issue. Power is delivered via a proprietary 7-pin cable that connects to the included controller hub. The hub requires one free PWM header and one 5V ARGB header (3-pin) on the motherboard. The fans are compatible with Lian Li's L-CONNECT 3 software, as well as major motherboard RGB ecosystems like ASUS Aura Sync, MSI Mystic Light, and Gigabyte RGB Fusion.

Product Info

Released in 2022, the Lian Li UNI FAN SL INFINITY 120 White 3Pack is available on Japan for approximately ¥10,791 (tax included). It occupies the mid-to-high-end market tier, valued for its daisy-chain convenience and infinity mirror aesthetics. Each fan draws only 3.5W, keeping total system power consumption low. The kit includes three fans, a controller hub, and necessary cables.

Best Use Cases

RGB-focused gaming builds: The infinity mirror LED effects are especially striking in cases with tempered glass side panels. L-CONNECT 3 allows granular control over lighting patterns, making it easy to match the rest of your setup. Clean cable management enthusiasts: The daisy-chain design reduces the number of fan cables from three to one, improving airflow and making future maintenance easier. * Quiet creative workstations: At 29 dBA under load, these fans remain unobtrusive during video editing or 3D rendering sessions, even when the system is under sustained load.

Things to Consider

This kit requires the proprietary controller hub, so it is not a drop-in replacement for standard 3-pin or 4-pin fans. Mixing with other fan brands may complicate control. Daisy-chaining is limited to four fans per hub; larger builds may need additional controllers. Plan your fan layout in advance if you are building a high-end water-cooling loop. Compared to competitors like Corsair LL120 or NZXT Aer RGB 2, the UNI FAN SL INFINITY offers easier cable management and a unique mirror aesthetic. However, reliance on L-CONNECT 3 software may be a drawback for users who prefer motherboard-native RGB control.
