Вентилатор 140mm, Noctua NF-A14x25r G2 PWM, 4-pin, 1500rpm

Noctua NF-A14x25r G2 PWM

Succeeding the award-winning NF-A15 and building on the technological innovations of the ground-breaking NF-A12x25, the NF-A14x25r G2 is Noctua’s next-generation round-frame 140mm flagship model: Made from Sterrox® LCP, its highly optimised Progressive-Bend impeller with winglets, Flow Acceleration Channels and Centrifugal Turbulator hub combined with a tip-clearance of only 0.7mm allow the NF-A14x25r G2 to further improve its predecessor’s renowned quiet cooling performance. This makes it not only a perfect fit for Noctua’s next-generation 140mm class heatsinks but also an excellent upgrade for existing cooler models such as the NH-D15(S) or NH-U14S series (Sx2-PP set recommended for push/pull configurations). The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 1500 to 1250rpm. Its ultra low-loss etaPERF motor with Smooth Commutation Drive 2 technology doesn’t only provide unprecedented energy efficiency and running smoothness but thanks to the new SupraTorque feature, it can also leverage extra torque headroom to keep the fan at its desired speed when working against back pressure, thereby ensuring even better performance on heatsinks.
