Product Description:

The Be Quiet! Silent Wings 4 140mm PWM High Speed is a premium case fan engineered to deliver high performance for demanding applications like radiators and heatsinks while maintaining virtually inaudible operation.

This 140mm fan operates at up to 1900 RPM, providing a strong airflow of 78.4 CFM. It is specifically optimised for maximum air pressure via silence-optimised fan blades, small tip clearance, and a fan frame with funnel-shaped air outlets. This design ensures that even at maximum speed, the noise level remains very low at just 29.3 dB(A). 

Its extremely quiet and smooth operation is facilitated by a highly efficient 6-pole fan motor and a long-life Fluid Dynamic Bearing (FDB), which provides a super-long lifespan of up to 300,000 hours. The fan includes two mounting options in the box-anti-vibration mounting for case use and hard plastic mounting for radiators/heatsinks.
