be quiet! Pure Wings 3 PWM Fan, Rifle Bearing, 140mm, White

This 140mm high-speed case fan is engineered for demanding cooling requirements, providing effective heat dissipation for both standard case installations and complex radiator setups. Operating via a 4-pin Pulse Width Modulation (PWM) connection, the fan speed dynamically adjusts based on thermal requirements, enabling consistent cooling efficiency. The unit achieves a maximum rotational speed of 1800 RPM, delivering 72.2 CFM of airflow and generating 2.44 mmH₂O of static pressure.

The design incorporates nine optimized blades and a closed-loop motor, which regulates the fan speed to maintain stability under varying system loads. Acoustic performance peaks at 30.5 dB at maximum rotation, balancing necessary air movement with controlled noise output. Reliability is addressed through the implementation of Rifle bearing technology, rated for an 80,000-hour Mean Time To Failure (MTTF), supporting long-term operation. The fan is supplied in white and includes four mounting screws.
