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.

Questions about this item

Should I choose the three-fan pack with controller or a single-fan version?

The three-fan pack includes a controller that handles power delivery, RPM reporting and wireless or motherboard control for all three fans, while a single fan would need a separate controller to use those features.

What does the 120 mm size mean for airflow in my case?

The 120 mm frame fits standard 120 mm mounting points and the reverse-blade design pushes air in the opposite direction to a regular fan, letting you create intake or exhaust patterns that suit your layout.

How does the 5V 3-pin ARGB and PWM connection limit control options?

The 5V 3-pin ARGB header lets motherboard software drive lighting while the PWM header controls speed, and the same receiver also supports L-Connect 3 wireless control so you can switch between wired and wireless modes.
