Lian Li UNI FAN SL-INF Flex 120mm Reverse Blade ARGB Fan 3 Pack White

Three-pack ARGB fan kit

This kit contains three 120 mm white case fans with reverse-blade design and addressable RGB lighting. A dedicated controller is included in the box for unified management. The fans suit builders who want coordinated airflow and lighting across multiple intake or exhaust positions. They are not intended for single-fan upgrades or builds that lack space for a controller hub.

Sustained-load behaviour

The reverse-blade layout is engineered to maintain steady airflow through restrictive areas such as radiators or dense mesh panels. PWM and wireless control paths let the system adjust speeds dynamically without sudden rpm spikes. Multi-zone lighting remains stable during extended operation because power delivery is handled by the controller rather than individual motherboard headers. Builds requiring variable-speed profiles tied to liquid-temperature sensors will need a separate sensor input not provided here.

5 V 3-pin ARGB + PWM control

Lighting is driven exclusively through a 5 V 3-pin ARGB header while fan speed uses standard PWM signalling, with an optional wireless link to L-Connect 3 software. Motherboards without a 5 V ARGB header cannot synchronise the lighting effects. The controller occupies one internal USB 2.0 header for software features, so boards lacking that header lose wireless and LCD functionality.
