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

This 140mm case fan is engineered for system cooling where minimizing operational volume is critical. It utilizes airflow-optimized blades designed to move 85 m³/h (49.8 CFM) of air while maintaining a low rotational speed of 900 RPM. The component maintains an acoustical output limited to 14.9 dB, making it a suitable choice for noise-conscious PC constructions. The design provides a maximum static pressure of 0.58 mmH2O, supporting effective air movement through restrictive case ventilation points.

Integrated Pulse Width Modulation (PWM) functionality allows the fan speed to be dynamically managed via a 4-pin connector, optimizing airflow relative to internal system temperature requirements. Durability specifications indicate a Mean Time To Failure (MTTF) of 80,000 hours, supported by the implementation of Rifle bearing technology. The fan frame includes rubberized elements specifically designed to absorb rotational vibration and prevent noise transmission into the PC chassis, focusing performance exclusively on case ventilation.
