be quiet! Pure Wings 2 PWM Fan, Rifle Bearing, 140mm, Black

This cooling fan is a 140mm unit designed for efficient system ventilation and heat management within a PC chassis or mounted on a radiator. It utilizes nine airflow-optimized fan blades intended to minimize air turbulence during operation. The design focuses on balancing effective air movement with low acoustic output, making it suitable for noise-sensitive builds. At maximum rotational speed, the fan moves 61.2 CFM of air while generating a static pressure of 0.76 mmH₂O.

Speed variation is managed via a 4-pin Pulse Width Modulation (PWM) connector, allowing the system to adjust the rotational speed up to 1000 RPM based on temperature demands. The unit employs a durable Rifle bearing technology rated for a Mean Time Between Failures (MTBF) of 80,000 hours, supporting long-term stability. Acoustically, the fan operates at a maximum reported noise level of 19.8 dB, maintaining quiet performance even when running at full capacity. The standard 140 x 140 x 25 mm dimensions ensure broad compatibility for both case and radiator mounting points.
