Product conception, design and quality control in Germany.\u003c\/p\u003e\u003cp\u003ePure 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 air resistance.\u003c\/p\u003e\u003cp\u003eThe fan frame outlet is newly designed to minimize air leaks. This benefits especially the radiator performance of Pure Wings 3 140mm PWM high-speed.\u003c\/p\u003e\u003cp\u003eTo 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.\u003c\/p\u003e\u003cp\u003eWith 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.

Every part and single detail contribute to the functionality and uncompromising performance. This has also been considered in the design of the fan.
