## Long description

be quiet! Pure Wings 3 140 mm PWM High-Speed Triple Pack contains three 140 mm case fans designed for PC cooling. Each fan delivers up to 1800 RPM, 122.6 m³/h airflow and a maximum static pressure of 2.44 mmH2O. The fans use rifle bearing technology and PWM control, operate across 5–13.2 V and are finished in black. This pack is suitable for improving airflow in high-performance and water-cooled systems where sustained fan speed and radiator performance matter.
Advantages
The closed loop motor maintains the target rpm even under resistance, ensuring consistent performance on radiators and behind fan grills. A redesigned fan frame and re-angled blades increase air pressure and reduce air leakage for improved cooling efficiency. Rifle bearing construction provides a long average lifespan (around 80,000 hours), and PWM support enables precise speed control down to low minimum rpm for quiet operation.
Suitable for
Case cooling for gaming and high-performance PCs
Radiator fans in liquid cooling loops
Replacement or upgrade of 140 mm system fans
Configurations requiring sustained high static pressure

How to use
Install each fan in a 140 mm fan mount following your PC case or radiator manufacturer’s instructions. Connect the fans to a PWM-capable fan header on the motherboard or to a compatible fan controller to enable automatic speed regulation. Ensure airflow orientation matches your intended intake or exhaust configuration. Secure the fans with the supplied screws and route cables to avoid contact with fan blades.
Usage recommendations
For optimal radiator performance, mount the fans as push or pull on the radiator faces with consistent orientation and use PWM control to balance cooling and noise. Regularly clean the fan blades and frame to maintain airflow and the closed loop motor’s ability to sustain rpm under resistance.
