Motor with closed-loop technology for constant speeds 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 works against a resistance, for example against a fan screen or a radiator, it rotates slowly. A closed control circuit continuously monitors the current fan speed and increases it to the target speed if required. As a result, the Pure wings 3 140 mm PWM high speed always work with the desired speed, no matter what air resistance. For a never before air pressure in its class A newly designed outlet on the fan frame minimizes air leakage. This is particularly noticeable in the use of Pure Wing 3 140 mm PWM high speed on radiators. Even the fan blades are optimized to achieve an even higher performance: Their angle is adjusted for even more air pressure. Pure wings 3 140 mm PWM high speed enable extraordinary performance. Optimized fan blades for high pressure With a remarkably high air pressure of up to 2.44mm/H2O the Pure wings 3 140 mm PWM high-speed is the best choice for water and air-cooled systems equally. The 9 fan blades optimized for the air flow provide adequate air pressure, so that this fan delivers excellent performance even in demanding configurations. Advanced appearance for a timeless classic Pure wings 3 140 mm PWM high speed does away with all necessary. Every single detail contributes to functionality and uncompromising performance. This is also taken into account in the design of the fan. All contours and angles serve a purpose and make Pure Wings 3 140 mm PWM high speed a timeless classic and an elegant supplement for each gaming PC. Makes Pure Wings 3 a long-time companion Pure wings 3 140 mm PWM high speed is designed for a long life. With the proven Rifle-bearing technology, this fan offers an average lifespan of 80,000 hours.
