Available in Two Colours Two Airflow Orientations

UNI FAN SL-INF Wireless is available in two colour options – black and white– and supports both standard and reverse airflow orientations to suit any build style or cooling setup. Offered in both 1-pack and 3-pack options for maximum flexibility.

Note: The controller will be included ONLY in 3 pack fans. As for the one pack fan users, controllers are now available to purchase separately.

Three Zones, Infinite Possibilities

Individually controlled lighting across the blade hub, dual side strips, and inner edge.

Asymmetrical Infinity Mirror Design

Each fan features a dual-style edge—tapered on one side, dual-rectangle on the other.

Flip the fan to show the perfect look, and customise each layer’s colour, brightness, and effect for total creative freedom.

Quiet Power, Built to Perform

The UNI FAN SL-INFINITY Wireless delivers high-performance cooling airflow. Its FDB design ensures smooth, quiet operation, which is perfect for radiators and dense front panels.

Seamless Signal, Smarter Power

The UNI FAN SL-INF Wireless is equipped with a wireless receiver with an upgraded 4-pin PWM cable for 12V power delivery and BIOS fan detection. The receiver also has an additional PWM tail cable to ensure stable power.

Note : Some MBs have a very low Over-Current Protection (OCP) threshold, making it easy to trigger OCP when the RGB lighting is set to bright colours and the fan ramps up in RPM. If a power shortage occurs even when both headers are connected, Lian Li suggest trying the upper header on the motherboard or relocating one of the 2-pin connectors to SATA power. Additionally, avoid connecting two or more channels to the same header area on the MB.

Note: UNI FAN SL-INF Wireless comes with an anti-static protective cap on the contact point to prevent static damage during handling and installation
