be quiet! Pure Wings 3 140mm PWM High-Speed Case Fan

The Pure Wings 3 140mm PWM high-speed delivers exceptional cooling performance for demanding PC builds. Engineered with a closed loop motor technology, this fan maintains consistent rpm regardless of resistance from radiators or fan grills, ensuring reliable airflow when you need it most.

Closed Loop Motor Technology

The innovative closed loop motor functions like cruise control, constantly monitoring and adjusting fan speed to maintain target rpm. When operating against resistance from heatsinks or radiators, the motor automatically compensates to deliver consistent performance. This ensures the Pure Wings 3 operates at your desired speed in any configuration.

Optimized for High Static Pressure

Achieving up to 2.44mm H2O air pressure, this fan excels in restrictive airflow environments. The redesigned fan frame minimizes air leaks at the outlet, while 9 optimized fan blades feature adjusted angles for maximum pressure generation. These improvements make the Pure Wings 3 140mm PWM high-speed ideal for both water cooling radiators and dense heatsink arrays.

Performance Specifications

Operating at 1800 rpm maximum speed, the fan delivers 72.2 CFM (122.6 m³/h) airflow while maintaining 30.5 dB(A) noise levels. The 4-pole motor with rifle bearing technology provides an 80,000-hour lifespan at 25°C. PWM control allows precise speed adjustment from minimum to maximum rpm for balanced performance and acoustics.

Durable Rifle Bearing Construction

Built with proven rifle bearing technology, the Pure Wings 3 ensures long-term reliability in continuous operation. The bearing design reduces friction and wear, contributing to the fan's 80,000-hour operational lifespan. This durability makes it suitable for 24/7 system operation.
