Lian Li UF-SLIN120-1B 120mm ARGB case fan

120 mm ARGB case fan with infinity mirror

The Lian Li UNI FAN SL-INFINITY is a single 120 mm case fan finished in black with addressable RGB lighting. Its centrepiece is an infinity mirror built from layers spaced 0.5 mm apart, framed by aluminium trim and side LED strips. The fan uses fluid dynamic bearings and is designed for builders who want strong visual impact alongside effective airflow. No controller is included in the box.

Thermals, noise and power draw in normal use

At typical speeds the fan delivers 61.3 CFM of airflow while producing a low 29 dBA noise level. Fluid dynamic bearings keep friction low, helping the motor run smoothly during everyday desktop workloads. The 25 mm thickness fits standard mounting points, and removable keylocks let you secure the fan directly to a radiator for CPU cooling. Daisy-chain connections simplify cable routing inside the case.

Behaviour under sustained load

When pushed to its 2100 rpm maximum the fan maintains the rated airflow figure without exceeding the quoted acoustic level. The modular pin-to-pad design keeps the daisy chain stable during long sessions, and L-Connect 3 software allows you to tune curves for continuous operation. The aluminium-trimmed frame resists vibration even at peak speed, preserving both cooling performance and the infinity mirror visual effect over extended periods.
