## Long description

The Lian Li UNI FAN SL-INF Wireless ARGB PWM Reverse Blade 140mm black is a 140mm chassis fan engineered for system cooling with integrated addressable RGB lighting and wireless control. It combines a reverse-blade impeller profile designed to shape airflow with PWM motor control for automated speed adjustment. The fan conforms to standard 140mm mounting dimensions and is compatible with modular fan ecosystems that support the UNI FAN SL-INF series, offering plug-and-play installation and synchronized lighting when used with compatible controllers.
Advantages
This 140mm fan provides controlled cooling through PWM speed regulation, allowing the system to balance airflow and acoustic performance automatically. The reverse-blade design alters airflow characteristics to improve static pressure and directional flow in typical PC layouts. Integrated addressable RGB lighting is accessible via wireless control for flexible illumination management without extra wired connections. The fan’s black frame and blade finish offer neutral styling suitable for a wide range of builds.
Suitable for
Case cooling in mid-tower and full-tower desktop PC builds
Radiator or heatsink use where a 140mm fan is required and reverse-blade flow benefits cooling
Systems requiring addressable RGB lighting with wireless control or modular fan integration
Users who want PWM-based automated fan speed regulation for noise and temperature management
Key specifications
Fan size: 140 mm standard chassis fan
Blade design: reverse-blade impeller for altered airflow profile
Speed control: PWM support for automatic fan speed regulation
Lighting: addressable RGB (ARGB) with wireless control capability
Color: black frame and blades
Mounting: fits standard 140mm screw holes and fan mounts
How to use
Mount the fan into a compatible 140mm location in the chassis or on a compatible radiator using standard screws. Connect the PWM fan connector to a motherboard fan header or PWM controller to enable automatic speed regulation. For addressable RGB lighting and wireless control, follow the manufacturer’s instructions to pair the fan with the compatible wireless controller or hub from the same modular ecosystem. Verify airflow direction before final assembly to ensure correct orientation for intake or exhaust roles.
Usage recommendations
For balanced cooling and acoustic results, use PWM control linked to motherboard temperature sensors or a fan controller profile. When installing multiple fans, maintain consistent airflow direction and configure ARGB synchronization through the compatible hub to achieve uniform lighting effects. Ensure adequate clearance around the fan and avoid routing cables over the blades to prevent interference.
