Normal Blade 120 mm ARGB Fan

The Lian Li UNI FAN SL Flex is a single 120 mm case fan with a normal blade design and white finish. It provides ARGB lighting controlled through a 5V 3-pin motherboard header while fan speed is managed via PWM. The package contains the fan only; no controller is included.

Builders Who Need a Daisy-Chain Fan Without

This unit suits builders expanding an existing UNI FAN SL setup or those who prefer direct motherboard ARGB and PWM control. It is not for buyers who require a bundled controller, a reverse blade variant for push-pull configurations, or a multi-fan kit in a single box.

120 mm Normal Blade Airflow Direction

The fan uses a normal blade orientation that moves air in the standard direction for intake or exhaust mounting. Selecting the correct blade type is essential because the reverse blade version moves air the opposite way and cannot be interchanged in the same cooling layout.

How do I choose between the normal blade and reverse blade versions?

Pick the normal blade version when you need standard airflow direction from front to back; choose reverse blade only if your build requires intake from the opposite side.

A 120 mm fan fits standard case mounts and radiator slots, delivering typical 120 mm airflow and static pressure for CPU coolers or case ventilation.
