be quiet! Pure Wings 3 120mm | PWM Reverse wit 3-pack

PURE WINGS 3 120mm PWM Reverse White 3-Pack is a set of three 120 mm computer case fans designed for side or bottom air intakes. Featuring reversed, airflow-optimized blades and PWM control, this triple pack delivers high airflow and reliable performance while maintaining low noise at very low minimum RPM. The fans use rifle bearing technology for extended lifespan and are produced with conception, design and quality control in Germany.

Advantages

The reversed fan blades are optimized for maximum airflow and reduced turbulence, providing higher air pressure suitable for intake positions such as side or bottom mounts. PWM support allows precise speed control and very quiet operation at low RPM. Built with rifle bearings, the fans offer long service life—on average up to 80,000 hours. The streamlined, functional design keeps the visible front of the fan aesthetically pleasing in showcase cases.

How to use

Install the fans in the case at the intended intake positions such as side or bottom mounts, aligning the airflow direction toward the inside of the case. Secure each fan with the supplied screws or compatible mounts, connect the PWM cable to a motherboard fan header or compatible controller, and configure fan curves in the BIOS or software to balance cooling performance and noise according to system needs. Ensure unobstructed airflow paths and clean dust filters regularly to maintain performance.

Recommendations

For optimal results, use this 3-pack as intake fans in a case with show-side panels or bottom openings. Pair with exhaust fans of similar performance and configure PWM curves to keep noise low while ensuring sufficient airflow. Regular maintenance—such as dusting and verifying secure mounting—will help maintain long-term reliability.
