Be Quiet! BL109 Pure Wings 3 140mm PWM high-speed are the perfect addition to demanding PCs with extraordinarily high performance and progressive features such as a speed-regulating closed loop motor.
Be Quiet! BL109 Pure Wings 3 140mm PWM high-speed features a closed loop motor. This technology is comparable with the cruise control in cars. When working against resistance, for example a fan grill or radiator, fans spin slower as a result. The closed loop motor technology constantly monitors the current fan speed and increases it to the target rpm, if necessary. As a result, Pure Wings 3 140mm PWM high-speed always operates at the desired speed, no matter the resistance.

Optimised to the Max
The fan frame outlet is newly designed to minimise air leaks. This benefits especially the radiator performance of Pure Wings 3 140mm PWM high-speed. To reach even higher performance, the fan blades are optimized as well: Their angle is adjusted to achieve even more air pressure, adding up to the extraordinary performance of Pure Wings 3 140mm PWM high-speed.
Iconic Design
Pure Wings 3 140mm PWM high-speed trims all the fat. Every part and single detail contribute to the functionality and uncompromising performance. This has also been considered in the design of the fan. All outlines and angles serve a purpose, making Pure Wings 3 140mm PWM high-speed a timeless classic and elegant addition to every gaming PC.
For Radiators and Heatsinks
With a remarkably high air pressure of up to 2.44mm/H2O, Pure Wings 3 140mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimised fan blades provide enough air pressure to make this fan work great even in demanding configurations.
Rifle Bearing Technology
Be Quiet! BL109 Pure Wings 3 140mm PWM high-speed is built to last. With the proven rifle bearing technology, on average, this fan offers a lifespan of a 80,000 hours.
