PURE WINGS 3 140mm PWM HS 3-Pack PERFORMANT, PROGRESSIVE, QUIET Pure Wings 3 140mm PWM high-speed Triple Pack is the perfect addition to demanding PCs with extraordinarily high performance and progressive features such as a speed-regulating closed loop motor. INNOVATIVE TECHNOLOGY Closed loop motor for persistent rpm Pure Wings 3 140mm PWM high-speed Triple Pack features a closed loop motor. This technology is comparable with the cruise control in cars. When working against resistance, for example a fan grill or radiator, fans spin slower as a result. The closed loop motor technology constantly monitors the current fan speed and increases it to the target rpm, if necessary. As a result, Pure Wings 3 140mm PWM high-speed Triple Pack always operates at the desired speed, no matter the resistance. OPTIMIZED TO THE MAX For unprecedented air pressure in its class The fan frame outlet is newly designed to minimize air leaks. This benefits especially the radiator performance of Pure Wings 3 140mm PWM high-speed Triple Pack. To reach even higher performance, the fan blades are optimized as well: Their angle is adjusted to achieve even more air pressure, adding up to the extraordinary performance of Pure Wings 3 140mm PWM high-speed Triple Pack. FOR RADIATORS AND HEATSINKS Fan blades optimized for high pressure With a remarkably high air pressure of up to 2.44mm/H2O, Pure Wings 3 140mm PWM high-speed Triple Pack is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimized fan blades provide enough air pressure to make this fan work great even in demanding configurations. ICONIC DESIGN Streamlined look makes it an instant timeless classic Pure Wings 3 140mm PWM high-speed Triple Pack trims all the fat. Every part and single detail contribute to the functionality and uncompromising performance. This has also been considered in the design of the fan. All outlines and angles serve a purpose, making Pure Wings 3 140mm PWM high-speed Triple Pack a timeless classic and elegant addition to every gaming PC. RIFLE BEARING TECHNOLOGY Makes Pure Wings 3 a long-lasting companion Pure Wings 3 140mm PWM high-speed Triple Pack is built to last. With the proven rifle bearing technology, on average, this fan offers a lifespan of 80,000 hours.
