be quiet! Silent Wings 4 PWM Fan, Rifle bearing, 140mm, White

This 140mm high-speed cooling fan is engineered for demanding system requirements, specifically targeting radiators and heatsinks where strong static pressure is essential for efficient heat exchange. The unit supports Pulse Width Modulation (PWM) functionality via a 4-pin connector, allowing the system to modulate rotational speed up to 1900 RPM for adaptive cooling based on real-time thermal load. At maximum operation, the fan achieves an airflow of 78.4 CFM, coupled with a static pressure rating of 2.36 mmH2O.

Acoustic output is limited to 29.3 dB when operating at the highest rotational speed, establishing a functional balance between heat dissipation effectiveness and audible noise generation. Longevity is managed by a durable Rifle bearing system, which contributes to an extended operational lifespan rated for 300,000 hours of continuous use. This component features a consistent white finish, providing builders with an aesthetically clean component suitable for color-coordinated PC system interiors.
