Lian Li’s UNI Fan SL-Infinity 140 is for builders who want high-performance cooling without a wiring nightmare. Its signature feature is the infinity mirror ring, a multi-layer halo of light that looks sophisticated, not gaudy. This is a fan designed to be seen.

Each fan packs 40 LEDs, offering deep customization through ARGB software. The real genius is in the connection. You can daisy-chain up to four fans together, linking them side-to-side. A single cable run from the cluster handles both power and lighting for the whole group. This cuts cable clutter dramatically inside your case. At 5.16 watts and 140mm, it moves air quietly and efficiently.

You will need a compatible ARGB header on your motherboard or a separate controller to manage the lighting effects. The single-pack is perfect for a rear exhaust upgrade, but for a full system, plan your purchase in multiples. The simplification it brings to a clean build is its most compelling feature.
