be quiet! Pure Wings 3 140mm PWM high-speed case fans
Pure Wings 3 140mm PWM high-speed are the perfect complement for demanding PCs with exceptionally high performance and advanced features such as a closed-loop motor for speed control.
Pure Wings 3 140mm PWM high-speed has a closed-loop motor. This technology is comparable to cruise control in cars. If the fan works against a resistance, for example against a fan grille or a radiator, it rotates more slowly. A closed control loop constantly monitors the current fan speed and increases it to the target speed if necessary. As a result, the Pure Wings 3 140mm PWM high-speed always operates at the desired speed, regardless of the resistance.
For radiators and heat sinks
With a remarkably high air pressure of up to 2.44 mm / H2O, the Pure Wings 3 140 mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimised fan blades provide enough air pressure for this fan to deliver outstanding performance even in demanding configurations.
Features:
- Innovative motor with closed-loop technology keeps the speed constant regardless of resistance
- Optimised fan frame for excellent performance on radiators
- Specially designed fan blades and optimised angle for exceptional air pressure
- Pure Wings 3 140mm PWM high-speed enables a very low minimum speed for very quiet operation
- Durable Rifle bearing with an operating life of 80,000 hours
