be quiet! Pure Wings 3 Reverse, 120mm, PWM Fan Kit, 3-pack, White

This kit provides three 120mm cooling fans engineered specifically for reverse airflow operation, a configuration intended for use as PC case intakes where the motor hub faces the interior of the system. Each fan utilizes a seven-blade design optimized to deliver efficient cooling performance, achieving a maximum airflow of 47.1 CFM and static pressure up to 1.17 mmH₂O. The reverse blade functionality is designed for specialized chassis configurations, such as side or bottom intake mounts, where aesthetics require the visually appealing side of the fan to face the outside.

System integration is managed through a 4-pin connector that supports Pulse Width Modulation (PWM), enabling dynamic speed control from 0 up to 1500 RPM in response to thermal load requirements. Noise output is contained, peaking at 28.5 dB at full rotational speed. Durability is addressed via Rifle Bearing technology, contributing to a rated Mean Time To Failure (MTTF) of 80,000 hours under standard operation, with each unit drawing 3.84 W of power at the rated 12 V input.
