140 mm infinity-mirror ARGB fan

The Lian Li UNI FAN SL Infinity Reverse is a single 140 mm case fan with a white frame and addressable RGB lighting on the centre mirror, side strips and rear logo ring. It uses fluid-dynamic bearings and a modular pin-to-pad connector that lets multiple units daisy-chain without extra cables. The fan is aimed at builders who want strong visual impact alongside effective airflow for radiators or case ventilation.

Sustained-load behaviour

At full speed the fan spins at 1600 rpm and moves 72.7 CFM while producing 28 dBA of noise. Fluid-dynamic bearings keep acoustic output steady during long sessions, and the 25 mm thick frame maintains static pressure for radiator mounting. Removable keylocks secure the fan to a radiator so vibration does not increase over time.

Compatibility checks

Verify your motherboard or controller has a standard 5 V ARGB header and a 4-pin PWM fan header for each daisy-chained unit. No controller is included, so software control via L-Connect 3 requires a compatible Lian Li hub or motherboard header. Ensure 140 mm mounting points and 25 mm clearance exist in the intended case or radiator location.

Questions about this item

How loud is the 140 mm fan when it runs at 1600 rpm all day?

The fan produces 28 dBA at full speed, which stays quiet enough for continuous use in a typical room.

What extra part must I already have to control the ARGB lighting and fan speed?

A compatible Lian Li controller and a motherboard 5 V ARGB header are required, because no controller is included with this single fan.

Will the 25 mm thick frame and daisy-chain connectors fit alongside my existing 140 mm fans?

Yes, the 25 mm thickness matches standard 140 mm slots and the modular pin-to-pad design lets you chain it with other UNI FAN SL-Infinity units.
