be quiet! Pure Wings 3 PWM Fan Kit, Rifle Bearing, 120mm, 3-pack, Black

This triple-pack includes three 120mm cooling fans designed for efficient thermal management within PC enclosures or radiator setups. Each unit is constructed with a standard 25mm thickness and achieves a maximum rotational speed of 1600 RPM. They are rated to move up to 84.8 m³/h (49.9 CFM) of air. Furthermore, the fans generate a static pressure of 1.45 mmH2O, which facilitates effective airflow through restrictive elements like dust filters or dense radiator fins.

Speed management is controlled via a 4-pin connector utilizing Pulse Width Modulation (PWM) support, enabling the system to dynamically adjust speeds based on temperature demands. This capability ensures the fans can operate quietly, generating a maximum noise output of 25.5 dB at full performance. The integrated Rifle Bearing technology contributes to enhanced longevity, providing a Mean Time to Failure (MTTF) rating of 80,000 hours and a reliable cooling solution.
