be quiet! Pure Wings 3 PWM Fan, Rifle Bearing, 140mm, Black

This 140 mm high-speed cooling fan is engineered for effective thermal management in demanding PC builds. It is constructed with nine redesigned fan blades and an optimized frame geometry intended to maximize both airflow and static pressure. Operating at its maximum speed of 1800 RPM, the fan delivers up to 72.2 CFM of airflow and a static pressure rating of 2.44 mmH₂O. This balanced performance profile ensures efficient heat dissipation when utilized either as case ventilation or when installed on radiators and heatsinks.

The unit includes 4-pin Pulse Width Modulation (PWM) support, allowing the system motherboard to regulate fan speed precisely between 0 and 1800 RPM based on system thermal requirements. Noise output peaks at 30.5 dB at full operating capacity. The integrated Rifle bearing technology contributes to operational stability and longevity, providing a Mean Time to Failure (MTTF) rating of 80,000 hours. The fan operates on a standard 12V system, requiring 6W of power during typical use.
