Lian Li UNI FAN SL-INF Flex 120mm Normal Blade ARGB Case Fan, Single Pack, Black

Single 120 mm ARGB fan with infinity mirror

The Lian Li UNI FAN SL-INF Flex is a single 120 mm case fan with a normal blade orientation and black finish. It ships without a controller, so the builder must provide a 5 V 3-pin ARGB header and a PWM header on the motherboard or use Lian Li wireless accessories. The infinity-mirror edge creates a multi-zone lighting effect that adds visual depth to the build.

Control depends on motherboard headers

Fan speed is managed through a standard 4-pin PWM connection while lighting runs on a 5 V 3-pin ARGB header, both supplied by the motherboard. Without a bundled controller the fan cannot be addressed through L-Connect 3 unless a separate L-Wireless receiver is added. Cable routing is simplified because only two motherboard cables are required per fan.

Normal blade direction determines airflow path

This unit uses a normal blade design, meaning air is pushed in the standard front-to-rear direction rather than reversed. Installers must match the blade orientation to the intended intake or exhaust role in the case; using a normal blade where a reverse blade is needed will direct airflow the wrong way.
