be quiet! Pure Wings 3 PWM Fan Kit, Rifle Bearing, 140mm, 3-pack, Black

This cooling fan package includes three 140 mm units engineered for efficient heat dissipation within PC enclosures. The fan design achieves a maximum airflow of 57.4 CFM (97.5 m³/h) and generates a static pressure of 0.96 mmH₂O. Utilizing a 4-pin connector, the fans support Pulse Width Modulation (PWM) control, allowing the system to modulate rotational speed between 0 and 1200 RPM based on thermal load.

The units are rated to produce a maximum noise level of 21.9 dB at full speed, maintaining a low acoustic profile under typical operating conditions. Durability is addressed through the implementation of a Rifle bearing system, contributing to a specified Mean Time To Failure (MTTF) rating of 80,000 hours. The fans operate at a rated voltage of 12 V, drawing 0.06 A of current, and are compatible with a voltage range spanning 5 V to 13.2 V. Each fan measures 140 mm in width and 25 mm in thickness.
