Product Description:

The Be Quiet! Pure Wings 3 140mm PWM High Speed is an ultra-quiet case fan designed for demanding PCs, offering extraordinarily high performance with progressive features such as an innovative closed loop motor and an optimised design for use on radiators.

This 140mm fan operates at a maximum rotation speed of 1800 RPM and delivers an airflow of 72.2 CFM at 100% PWM. A key technological feature is the closed loop motor, which constantly monitors the fan speed and adjusts it to maintain the target RPM regardless of resistance (such as from a radiator or fan grill), comparable to cruise control in a car. 

The fan frame outlet and newly designed fan blades are optimised to minimise air leaks and create an extraordinary air pressure of up to 2.44 mm/H2O, making it an excellent choice for both water-cooled and air-cooled systems. Despite its power, the fan maintains ultra-quiet operation, with a maximum noise level of 30.5 dB(A). Its long-life Rifle Bearing technology ensures an operating lifespan of 80,000 hours.
