Fan Lian Li SL-INFINITY 12 cm Black 2100 RPM 29 dB

The Lian Li SL-INFINITY 120 mm case fan combines the SL and AL series design with a centered infinity mirror and side-frame ARGB strips for multi-layer lighting effects. It is a 120 mm black fan that reaches up to 2100 RPM, delivers up to 61.3 CFM airflow with 2.66 mmH2O static pressure, and operates at a reported noise level of 29 dB. The fan uses a Fluid Dynamic Bearing for improved durability and quiet operation, suitable for high-performance PC cooling.

Advantages

The SL-INFINITY fan provides layered ARGB illumination through a centered circular infinity mirror and dual side LED strips, while aluminum trim elements create a three-dimensional indented appearance. Performance-wise, the fan balances high airflow and static pressure for case ventilation and radiators, and the Fluid Dynamic Bearing reduces operational noise and increases lifespan.

Suitable for

• Case ventilation in mid-tower and full-tower PC builds
• Cooling radiators and AIO liquid coolers
• Systems where ARGB lighting is desired for aesthetic customization

How to use

Install the fan in the desired fan mounting position in your PC case, aligning the airflow direction with your case cooling plan. Connect the ARGB and power connectors to compatible headers on the motherboard or controller following manufacturer pinouts. Secure the fan using the supplied screws, then configure fan curves and ARGB lighting in BIOS or compatible control software to achieve the desired balance between cooling performance and noise.

Recommendations

For optimal cooling, use the SL-INFINITY fan in push or pull configurations on radiators with another matched-speed fan, and set a PWM profile that increases RPM under load to maintain temperatures while limiting idle noise. Ensure ARGB headers and connectors are compatible with your motherboard or use an ARGB controller if required.
