Product Overview

The be quiet! Silent Wings 4 140mm PWM White is a 140 mm case fan rated at just 13.6 dB at its top speed of 1,100 RPM. It moves 87.2 m³/h (51.3 cfm) of air at up to 0.92 mmH2O static pressure, helped by a 6-pole motor, a fluid dynamic bearing and a frame with a small gap to the blades and funnel-shaped air outlets.

This fan suits quiet, high-end builds where a white fan matters, with a glossy white fan sticker. Its blades are optimised for radiators and heatsinks as well as case airflow, and 4-pin PWM control with a 5 to 13.2 V range allows fine speed adjustment. Push-pin anti-vibration mounts are included, with screws as an alternative fixing, plus rubber and plastic corners and a SATA multi-voltage adapter. Rated MTTF is 300,000 hours.
