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

This 140mm fan is designed to function as an efficient cooling component for PC systems, suitable for both chassis ventilation and integration with radiators. It achieves a maximum rotational speed of 1200 RPM, resulting in an airflow output of 57.4 CFM (97.5 m³/h). The blade geometry is calibrated to produce a static air pressure of 0.96 mmH2O, ensuring adequate performance even when pushing air through restrictive filters or fins.

Acoustic performance remains controlled, registering a peak noise level of 21.9 dB during full operational output. The fan utilizes a Rifle bearing mechanism, contributing to an extended operational lifespan rated at 80,000 hours Mean Time To Failure (MTTF). System integration is facilitated by the implementation of Pulse Width Modulation (PWM) control, enabling precise speed adjustments based on thermal load requirements.

The physical dimensions of the unit are 140 x 140 x 25 mm, aligning with standard 140mm mounting points within PC cases. This unit draws 0.06 A of current at a rated 12 V, with a typical power consumption of 3.6 W. The retail package includes necessary mounting hardware for direct installation into compatible computer enclosures or cooling fixtures.
