be quiet! Pure Wings 3 140 mm PWM High Speed Fan, Top Speed, Low Minimum Optimised Fan Frame, Exceptionally Air Pressure, Very Quiet Operation, Rifle, BL109

Pure Wings 3 140 mm PWM high-speed has a closed-loop motor. This technology is comparable to cruise control in cars. When the fan works against a resistor, for example against a fan grille or radiator, it rotates slower. A closed loop constantly monitors the current fan speed and increases it to the target speed if necessary. This means that the Pure Wings 3 140 mm PWM high-speed always works at the desired speed, no matter what resistance. The outlet on the fan frame minimises air leaks. This is particularly noticeable when using the Pure Wings 3 140mm PWM high-speed on radiators. The fan blades are also optimized to achieve even higher performance: their angle is adjusted for even more air pressure. Pure Wings 3 140 mm PWM high-speed is capable of exceptional performance. With a high air pressure of up to 2.44 mm/H2O, the Pure Wings 3 140 mm PWM high-speed is the best choice for water and air-cooled systems alike. The 9 fan blades optimized for airflow provide enough air pressure to deliver outstanding performance in demanding configurations. Pure Wings 3 140 mm PWM high-speed dispenses with all unnecessary. Every single detail contributes to functionality and uncompromising performance. This is also taken into account when designing the fan. All contours and angles serve a purpose and make Pure Wings 3 140mm PWM high-speed a timeless classic and an elegant addition to any gaming PC. Pure Wings 3 140 mm PWM high-speed is designed for a long service life. Featuring proven Rifle bearing technology, this fan offers an average lifespan of 80,000 hours.
