Product Description
"Motor with closed-loop technology for consistent speedsThe Pure Wings 3 140-mm PWM high-speed has a closed-loop motor.
This technology is comparable to the cruise control in cars.
If the fan is operating against a resistor, such as a fan grille or radiator, it will spin more slowly.
A closed loop continuously monitors the current fan speed and increases it to the target speed if necessary.
As a result, the Pure Wings 3 140-mm PWM high-speed always works at the desired speed, regardless of the resistance.
Includes three fansThe innovative motor with closed loop technology ensures that the speed remains constant, regardless of the level of resistanceOptimised fan frame for outstanding performance on radiatorsRedesigned fan blades and optimised angles for exceptional air pressurePure Wings 3 fans enable a very low minimum speed for very quiet operationLong-lasting rifle bearing with an operating life of 80,000 hours"
