be quiet! Light Wings High-Speed, 140mm, PWM, Rifle Bearing, ARGB Fan, Black

This 140mm high-speed case fan is engineered for performance, providing system cooling with a maximum rotational speed of 2200 RPM. The unit is designed to deliver substantial airflow, rated at 71.7 CFM (121.82 m³/h), while generating a static pressure of 2.3 mmH₂O. This combination makes the fan suitable for use as general case ventilation or mounted on radiators, where air resistance may be higher. The impeller incorporates nine optimized blades to facilitate efficient air movement across various cooling configurations.

Speed regulation is managed through a 4-pin Pulse-Width Modulation (PWM) connector, allowing the system to dynamically adjust performance based on thermal requirements. The fan maintains a maximum operating noise level of 31 dB at peak speed, balancing output with acoustic consideration. It utilizes durable Rifle bearing technology, providing a Mean Time to Failure (MTTF) rating of 60,000 hours. Power input requires a standard 12V DC connection, drawing a rated current of 0.67A and consuming 4.68W under typical operation.
