Be Quiet! Ventilator BE QUIET PURE WINGS 3 140mm PWM HS, BL109 cijene

Pure Wings 3 140mm PWM highspeed are the perfect complement for demanding PCs with exceptionally high performance and advanced features such as a closedloop motor for speed control.

Pure Wings 3 140mm PWM highspeed has a closedloop 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 highspeed 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 highspeed is the best choice for watercooled and aircooled systems alike. The 9 airflowoptimised fan blades provide enough air pressure for this fan to deliver outstanding performance even in demanding configurations.

Features:

• Innovative motor with closedloop 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 highspeed enables a very low minimum speed for very quiet operation
• Durable Rifle bearing with an operating life of 80,000 hours
