120mm PWM High-Speed Fan

The be quiet! Light Wings 120mm PWM High Speed is a single case fan built for builders who want strong airflow and addressable RGB lighting in a standard 120mm frame. It suits radiators, heatsinks or general chassis intake and exhaust where a balance of pressure and quiet running is needed.

Build Integration

The fan mounts in any 120mm case slot and connects via a standard 4-pin PWM header so the motherboard controls speed automatically between 2500 and 2999 RPM. Its 25mm thickness fits typical radiator and heatsink stacks, while the rifle bearing keeps friction low without requiring a separate fan controller.

Lighting and Durability

Eighteen ARGB LEDs on both front and rear surfaces let the illumination sync with motherboard software for unified colour effects. The seven silence-optimised blades deliver up to 55 CFM at 2.6mm H₂O static pressure while the rated noise stays between 30 and 35 dBA, and the bearing is rated for 60,000 hours of operation.
