BE QUIET! Silent Wings 4 120mm PWM white

The Silent Wings 4 120mm PWM White is a 120 mm case fan from be quiet! designed to run almost inaudibly while still delivering strong airflow. Its fan blades are optimised for low noise, and the funnel-shaped air intake along with a narrow gap between frame and blades supports high air throughput. Running at 1600 rpm with a noise level of 18.9 dB, it suits demanding systems as well as radiators and heatsinks.

A six-pole motor and fluid dynamic bearing (FDB) help reduce vibration and resonance, and the bearing is rated for up to 300,000 hours of service life. Mounting is possible either with the pre-installed vibration-damping mounts or with plastic brackets, which are particularly suited to radiators and heatsinks.

Its fully white design, with a 25 mm thickness, blends well into light-coloured PC builds.
