Motor with closed-loop technology for constant speeds. The Pure Wings 3 120 mm PWM High-Speed features a closed-loop motor. This technology is comparable to cruise control in cars. When the fan encounters resistance, such as from a fan grille or radiator, it slows down. A closed feedback loop continuously monitors the current fan speed and increases it as needed to reach the target speed. As a result, the Pure Wings 3 120 mm PWM High-Speed always operates at the desired speed, regardless of air resistance. A newly designed outlet on the fan frame ensures unprecedented air pressure in its class, minimizing air leaks. This is particularly noticeable when using the Pure Wings 3 120 mm PWM High-Speed on radiators. The fan blades are also optimized for even higher performance: their angle is adjusted for increased air pressure. Thus, the Pure Wings 3 120 mm PWM High-Speed is capable of exceptional performance. Optimized fan blades for high pressure. With an impressive air pressure of up to 2.41 mm/H2O, the Pure Wings 3 120 mm PWM High-Speed is the best choice for both water and air-cooled systems. The 9 fan blades optimized for airflow provide sufficient air pressure, ensuring that this fan delivers excellent performance even in demanding configurations. Advanced appearance for a timeless classic. The Pure Wings 3 120 mm PWM High-Speed eliminates all unnecessary elements. Every single detail contributes to functionality and uncompromising performance. This is also reflected in the fan's design. All contours and angles serve a purpose, making the Pure Wings 3 120 mm PWM High-Speed a timeless classic and an elegant addition to any gaming PC. Makes the Pure Wings 3 a long-term companion. The Pure Wings 3 120 mm PWM High-Speed is designed for a long lifespan.
