Single 120 mm Reverse-Blade ARGB Fan

This Lian Li UNI FAN CL Flex unit is a 120 mm case fan with reverse blade orientation and addressable RGB lighting. It is sold as a single pack in black and is designed for builders who need one additional fan to complete or refresh a cooling loop. The compact FLEX receiver handles power delivery and RPM reporting while keeping cable routing simple.

Suits single-slot upgrades; not for multi-fan kits

The fan targets enthusiasts who want wireless speed and lighting adjustment via L-Connect 3 or motherboard PWM and 5 V 3-pin ARGB sync. It suits cases that require a reverse airflow direction. Builders planning a multi-fan daisy-chain should look elsewhere because no controller is bundled and only one fan is supplied.

No controller included

The package contains the fan and FLEX receiver only; a separate UNI FAN controller must be sourced to enable daisy-chaining and centralised management. Without that controller the fan runs standalone through motherboard headers or wirelessly. Verify the airflow direction matches your case layout before ordering.

Questions about this item

What clearance does the 120 mm fan need inside the case?

The 120 mm frame fits standard 120 mm mounting points; allow space for the reverse-blade rotor and the daisy-chain cable running to the next fan.

How do I connect the fan for PWM and ARGB control without the controller?

Plug the 5 V 3-pin ARGB header and the PWM header into the motherboard, then route the daisy-chain cable to the next fan; the Flex receiver handles power and RPM reporting.

When should I replace the fan or its cables?

Replace the fan if bearing noise rises or airflow drops; inspect the daisy-chain cables during upgrades and swap any with damaged connectors or frayed wires.
