be quiet! Pure Wings 3 (3, Black, 120 mm PWM)

Pure Wings 3 120mm PWM high-speed Triple Pack incorporates a closed loop motor. This technology is comparable to the cruise control of cars. When working against a resistor, for example a fan grille or a radiator, the fans rotate slower as a result. 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 120mm PWM high-speed Triple Pack always runs at the desired speed, no matter the resistance. The fan frame outlet is newly designed to minimize air leakage. This especially benefits the performance of the Pure Wings 3 120mm PWM high-speed Triple Pack radiator. For even greater performance, the fan blades have also been optimized: Its angle is adjusted for even more air pressure, adding to the extraordinary performance of Pure Wings 3 120mm PWM high-speed Triple Pack. With an extraordinarily high air pressure of up to 2.4 mm/H2O, Pure Wings 3 120mm PWM high-speed Triple Pack is the best choice for both water and air cooled systems. The 9 airflow optimized blades provide enough air pressure for this fan to perform flawlessly even in demanding configurations. Pure Wings 3 120mm high-speed PWM Triple Pack eliminates all the unnecessary. Every part and every detail contributes to uncompromising functionality and performance. This has also been taken into account in the design of the fan. All contours and angles serve a function, making the Pure Wings 3 120mm high-speed PWM Triple Pack a timeless classic and a stylish addition to any gaming PC. Pure Wings 3 120mm PWM High-Speed Triple Pack is made to last. With proven rifle bearing technology, this fan delivers an average lifespan of 80,000 hours.
