Lian Li UNI FAN TL Flex 120mm Reverse Blade ARGB

The Lian Li UNI FAN TL Flex is a 120mm case fan designed for PC builders who want flexible control over cooling and lighting. It features a reverse blade design with an infinity mirror lighting effect. The fan operates without an included controller, connecting directly to motherboard headers for PWM speed and 5V ARGB synchronization.

Suits builders using motherboard PWM

This single fan suits users who already own a compatible motherboard with a 5V 3-pin ARGB header and a 4-pin PWM header for direct control. It also supports wireless operation via an optional L-Wireless receiver. Builders who need a controller in the box or who prefer a standard blade orientation for traditional intake airflow should consider other options.

Reverse blade airflow reaches 83.4 CFM at 2300 RPM

The LCP blades and tight 0.6mm gap deliver 83.4 CFM airflow with 2.66mmH2O static pressure at speeds up to 2300 RPM. FDB bearings and copper shielding keep operation quiet at high speed. The reverse blade direction moves air opposite to standard fans, so verifying the required airflow path for your specific case layout is the deciding factor before purchase.

Questions about this item

What motherboard header does the 5 V 3-pin ARGB connector plug into?

It connects to a standard 5 V 3-pin addressable RGB header on the motherboard for lighting control.

How is the fan secured in the case and what step is often missed?

Mount the fan with four screws through the 120 mm frame; the critical step is fully inserting and locking the FLEX receiver so the data and power contacts seat correctly.

What maintenance will the FDB bearing need over time?

The fluid-dynamic bearing is sealed and rated for continuous operation up to 2300 RPM, so no lubrication or servicing is required during its service life.
