Single 140mm ARGB fan for Lian Li ecosystems

The Lian Li UNI FAN AL140 V2 is a 140mm case fan with a 25mm frame and addressable RGB lighting. It connects via a standard 4-pin PWM header for speed control and a 5V 3-pin ARGB header for lighting. The white finish suits bright or monochrome builds.

Builders expanding a UNI FAN daisy chain

This single pack is intended for owners of a Lian Li UNI FAN controller who need one more fan to reach a cluster limit of six. Without the separate controller the ARGB lighting and unified speed curves cannot be synchronised. Buyers starting a new loop should purchase a kit that includes the controller.

Controller-dependent interlocking system

The fan uses a keylock daisy-chain block that carries both PWM and ARGB signals to the controller through two cables. Each controller port supports up to six fans and a maximum of sixteen fans total. The slimmer connector improves clearance against radiators.

Questions about this item

Should I buy the single white fan or look for a multi-pack?

The single pack contains one 140 mm white fan without a controller; multi-packs or the separate controller kit are required to run more than one fan or to use the daisy-chain features.

What does the 140 mm size mean for airflow in my build?

A 140 mm fan moves more air at lower RPM than a 120 mm unit, so it cools radiators and heatsinks effectively while staying quieter in typical case positions.

Does the 4-pin PWM connector limit speed control or lighting sync?

The 4-pin PWM header gives the motherboard full speed control, while the ARGB lighting runs on a separate 3-pin 5 V header and syncs with standard motherboard RGB software.
