Engine with closed loop for constant rotation Pure Wings 3 120mm PWM high-speed has an engine working in a closed loop. This technology is comparable to the speed in cars. Resistance fans, such as fan grates or radiators, rotate slower. Engine technology in a closed loop continuously monitors the current fan speed and increases it to target speeds if necessary. As a result, Pure Wings 3 120mm PWM high-speed always works at desired speed, regardless of resistance. Extraordinary air pressure in this class The vent frame is designed to minimize air leaks. This is particularly beneficial for Pure Wings 3 120mm PWM high-speed work efficiency on heat sinks. For even higher performance, fan blades are also optimized: Their angle is adjusted to achieve even higher air pressure, increasing the performance of Pure Wings 3 120mm PWM high-speed. For radiators and radiators With extremely high air pressure up to 2.41mm/H2O, Pure Wings 3 120mm PWM high-speed is the best choice for both water-cooled and air-cooled systems. 9 fan blades with optimized airflow provide sufficient air pressure to make the fan work great even in demanding configurations. Cultural Design Pure Wings 3 120mm PWM high-speed is completely optimized. Each part and single detail contributes to functionality and uncompromising performance. This was also included in the fan design. All contours and angles have their purpose, making Pure Wings 3 120mm PWM high-speed is a timeless classic and elegant addition to any gaming computer. Rifle bearing technology Pure Wings 3 120mm PWM high-speed is built for durability. Thanks to proven Rifle bearing technology, this fan offers an average of 80,000 working hours.
