Single 120mm ARGB fan for case builds

The Lian Li UF-SL120-1B is a single 120mm case fan with ARGB lighting in a black finish. It is designed for builders who want to add one addressable RGB fan to a compatible chassis without purchasing a multi-pack or bundled controller.

Daisy-chain mounting simplifies cable routing

Each fan uses a slide-on connector system that lets you link up to 3 units in a row, reducing the number of cables running back to the motherboard or a separate hub. Because no controller is included, the ARGB signal and power must come from a 5V addressable header on your motherboard or a compatible third-party hub.

Verify 5V ARGB header and 25mm clearance

Before ordering, confirm your motherboard has a free 5V 3-pin ARGB header to drive the lighting effects. Also check that your case or radiator mounting points accept a 25mm thick 12cm fan, as thicker models will not fit in slim clearance areas.

Questions about this item

How can I confirm the ARGB lighting is working after connecting the fan to a compatible motherboard header?

Connect the ARGB cable to a 5V 3-pin header on your motherboard and use the board's RGB software to verify the LEDs illuminate and change colour.

What is included in the package and what must be purchased separately to control the fan?

The box contains one 120mm black ARGB fan; a separate Lian Li UNI FAN controller or a motherboard with a 5V ARGB header and 4-pin PWM header is required for control.

Which version should I choose if I already own a UNI FAN controller and only need to expand my setup?

Select the single-fan UF-SL120-1B pack, which adds one 25mm thick 120mm ARGB fan without duplicating the controller you already have.
