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

These 120 mm cooling fans are supplied in a triple pack and feature a specialized reverse blade design, optimizing them for system intake applications where the fan must be mounted to draw air into the chassis. This geometry ensures the intended direction of airflow when utilized in locations such as the side or bottom of a PC case. The design targets a combination of airflow, rated at 47.1 CFM, and static pressure, peaking at 1.17 mmH2O, making the fans suitable for case ventilation or use on restricted cooling surfaces.

Control is managed through a 4-pin connector supporting Pulse Width Modulation (PWM), allowing for dynamic speed adjustment across the 0 to 1500 RPM range based on thermal demand. Utilizing Rifle bearing technology, the units are rated for a Mean Time To Failure (MTTF) of 80,000 hours, supporting long-term stability and function. At peak performance, the acoustic output is measured at 28.5 dB, positioning the fans for integration into noise-optimized computer systems.
