PURE WINGS 3
140mm PWM HS
Performant, progressive, quiet
Pure Wings 3 140mm PWM high-speed are the perfect addition to demanding PCs with extraordinarily high performance and progressive features such as a speed-regulating closed loop motor.
Innovative closed loop motor keeps the rpm no matter the air resistance
Optimized fan frame for outstanding performance on radiators
Newly designed fan blades and re-arranged angle for extraordinary air pressure
Pure Wings 3 140mm PWM high-speed can be operated with very low minimum rpm for very quiet operation
Long life rifle bearing gives an operating lifetime of 80,000 hours
Product conception, design and quality control in Germany
INNOVATIVE TECHNOLOGY
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. 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.
OPTIMIZED TO THE MAX
For unprecedented air pressure in its class
The fan frame outlet is newly 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.General data
