BE QUIET! Silent Wings 4 120mm PWM high-speed white

The Silent Wings 4 120mm PWM High-Speed in white is a 120 mm case fan from be quiet! that combines near-silent operation with strong airflow. It runs at up to 2500 rpm, measures 25 mm in thickness and connects via a 4-pin PWM header. Its fully white design suits builds with a matching colour scheme, and it can be mounted in a case or on a radiator or heatsink.

The fan blades are optimised for high pressure, while the narrow gap between blades and frame and the funnel-shaped air intake support strong airflow. A six-pole motor and fluid dynamic bearing reduce vibration and resonance, and the manufacturer rates the bearing for up to 300,000 hours of service life. Vibration-damping mounts and screw fixing make installation straightforward.

Rated at a maximum of 31.2 dB, the fan is well suited to quiet systems that still need solid cooling performance.
