Lian Li UNI FAN CL Flex 120mm Normal Blade ARGB 3 Pack Controller White

Normal blade airflow

This three-pack of 120 mm white case fans uses a normal blade design that pushes air in the standard direction. A compact Flex receiver is included to handle power delivery and RPM reporting for the whole set. Wireless control lets you adjust fan speed and ARGB lighting without extra cables. The kit targets builders who want a clean, cable-reduced installation.

Upgrade from single-controller kits

The Flex receiver replaces older standalone controllers by combining wireless operation with motherboard 5 V 3-pin ARGB and PWM sync in one small unit. It is worth the jump when you want both software ecosystems available simultaneously. Existing SL Wireless and CL Wireless fans remain compatible, so mixed-generation arrays work without extra hardware. Buyers who need reverse-blade airflow for specific radiator mounting cannot use this version.

Build integration

Each fan connects to the supplied receiver, which then links to a motherboard ARGB header and a PWM header for synchronized control. The wireless path frees up internal USB headers that older controllers occupied. White frames and blades suit light-themed builds while the 120 mm size fits most standard fan mounts. Systems that lack a 5 V ARGB header or PWM header cannot use the motherboard sync features.
