be quiet! Shadow Wings 2 PWM Fan, Rifle Bearing, 140mm, White

This 140mm cooling fan is engineered specifically for use in PC cases where acoustic performance is prioritized. The unit utilizes a rifle bearing mechanism designed to promote consistent rotation and extend the operational lifespan, rated for 80,000 hours Mean Time To Failure (MTTF). The maximum rotational speed is limited to 900 RPM, resulting in a maximum reported noise level of 14.7 dB under load.

Airflow management is handled by nine specifically optimized blades, generating an airflow capacity of 85 m³/h (49.8 CFM) and a static pressure of 0.58 mmH2O. The fan supports Pulse Width Modulation (PWM) control, integrating with the system motherboard via a 4-pin connector to allow dynamic speed adjustment based on current thermal requirements. The unit operates on a 12V supply, drawing 0.3A for a typical power consumption of 3.6W.
