## Summary description

The Lian Li UNI FAN SL-INF 120 is a 120mm case cooling fan with ARGB lighting and PWM speed control. Designed for PC cooling, it provides adjustable fan speed via PWM and customizable addressable RGB illumination. Suitable for improving airflow in chassis, radiators and CPU coolers, it offers easy integration with compatible motherboards and Lian Li UNI fan ecosystem.

## Long description

The Lian Li UNI FAN SL-INF 120 ARGB PWM 120mm is a case cooling fan designed for chassis airflow, radiator cooling and CPU cooler support. It features PWM-controlled fan speed for automated thermal response and addressable RGB illumination for customizable lighting effects. The fan is compatible with PWM motherboard headers and the Lian Li UNI FAN ecosystem for simplified connection and synchronized lighting and speed control.
Advantages
The fan combines PWM speed control with addressable RGB LEDs, allowing the system to balance noise and cooling performance automatically while offering per-fan lighting customization. Its 120mm form factor and optimized blade design provide efficient airflow and static pressure suitable for case ventilation and mounting on radiators. The modular connection design reduces cable clutter and facilitates installation when used with other compatible UNI FAN components.
Suitable for
Improving case airflow in mid-tower and full-tower PC chassis
Mounting on AIO radiators or custom water-cooling radiators
Supplementing CPU air coolers that accept 120mm fans
Building synchronized ARGB lighting setups with compatible motherboards or controllers
Key specifications
Fan size: 120 mm
Control method: PWM speed control
Lighting: Addressable RGB (ARGB) per fan
Connection: Standard PWM fan header compatibility and UNI FAN modular connectors
Application: Case ventilation, radiator and CPU cooler support
How to use
Install the fan into the case, radiator or CPU cooler using the appropriate mounting screws and orientation for intake or exhaust airflow. Connect the PWM power cable to a motherboard fan header supporting PWM control to allow automatic speed adjustments based on system temperatures. Connect the ARGB lighting connector to a compatible addressable RGB header or Lian Li controller to enable lighting control and effects. When used in a UNI FAN configuration, attach the modular connectors to link multiple fans for unified power and lighting management.
Usage recommendations
For optimal performance, set the PWM curve in the motherboard or fan controller to match your cooling needs—steeper curves for lower idle noise, flatter curves for consistently higher airflow. Ensure airflow direction matches the intended cooling path, and maintain clearance from cables and components to avoid interference with fan blades. When using multiple fans, synchronize ARGB settings through motherboard software or the Lian Li ecosystem to achieve consistent lighting and simplified control.
