Be Quiet! Pure Wings 3 120mm PWM Triple Fan Pack

Closed loop motor for persistent RPM Closed loop motor for persistent RPM 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. Optimized Fans The fan frame outlet is designed to minimize 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. 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. 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. OPTIMIZED FRAME: The fan frame outlet designed for peak performance on radiators AIRFLOW: 7 airflow-optimized fan blades not only reduce noise, but ensure performance under demanding configurations QUIET PERFORMANCE: Pure Wings 3 can be operated with very low minimum rpm for very quiet operation German Design | German Engineering | German Quality | German Performance
