Our take

4.5

The Lian Li Uni Fan SL120 stands out as a premium case fan that blends strong performance with striking aesthetics. Its reverse blade design delivers solid airflow and static pressure, making it versatile for both case ventilation and radiator use. While the proprietary daisy-chain system and reliance on L-Connect software may frustrate some users, the reduced cable clutter and seamless multi-fan integration make it a worthwhile investment for builders prioritizing clean aesthetics and vibrant RGB lighting.

Full review

The Lian Li Uni Fan SL120 is a case fan built specifically for PC enthusiasts who care as much about visual presentation as they do about airflow performance. Each 120mm fan features a translucent frame paired with an integrated addressable RGB light ring that wraps around the fan blades, producing a smooth, diffused glow rather than isolated points of light. The SL120 uses a fluid dynamic bearing designed for quiet, long-lasting operation, and its blade geometry is engineered to balance static pressure with airflow, making it versatile enough for use on radiators, as intake fans, or as exhaust fans within a typical ATX or ITX build.

What sets the Uni Fan SL120 apart from ordinary case fans is Lian Li's daisy-chain connection system, which allows multiple fans to be linked together using small L-shaped connectors between each unit. This design eliminates the usual tangle of individual ARGB and PWM cables, since only the first fan in the chain needs to be wired to the motherboard for both power and lighting control. Builders can expand a loop by simply snapping on additional SL120 units, or step up to SL-INF versions with infinity mirror lighting for larger installations, all while keeping cable management clean and consistent across the case interior.

From a practical standpoint, the SL120 ships with mounting hardware compatible with standard fan brackets, radiators, and case panels, and it supports PWM speed control for fine-tuned adjustment between silent operation and maximum cooling output. Lighting is addressable per fan, syncing with major motherboard ecosystems like ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, and ASRock Polychrome, or it can be controlled independently through Lian Li's own L-Connect software. Whether purchased as a single fan for a small upgrade or as part of a multi-fan kit for a full case refresh, the Uni Fan SL120 is positioned as a cooling component that blends thermal performance with the kind of cohesive RGB aesthetic that custom PC builders specifically seek out.
