Lian Li UNI FAN SL Flex 120mm Reverse Blade ARGB 3 Pack Controller Black

Three-Fan ARGB Kit with Controller

This Lian Li UNI FAN SL Flex set includes three 120 mm reverse-blade fans and a dedicated controller in a single black package. The bundle targets builders who want synchronised lighting and simplified cable routing inside a compatible case. PWM and wireless control paths are both supported through the included receiver.

Control Limited to 5 V 3-Pin ARGB and PWM

Lighting synchronisation relies on a motherboard 5 V 3-pin ARGB header, while speed regulation uses a standard PWM connection or the L-Connect 3 wireless app. The receiver handles power delivery and RPM reporting, but no other control protocols or voltage standards are provided. Builders without a 5 V ARGB header cannot use motherboard lighting sync.

Check for 5 V ARGB Header and Case Clearance

Verify that your motherboard has a 5 V 3-pin ARGB header if you plan to sync lighting through board software. Ensure the chassis has mounting points for three 120 mm fans and enough depth for the controller and cabling. This kit is not suited for systems lacking a 5 V ARGB header or for builds restricted to 4-pin 12 V RGB ecosystems.
