PWM
The NF-A6x25 is a highly optimised, quiet fan in premium quality with a size of 60 x 25 mm. The PWM version is equipped with the NE-FD1-IC developed by Noctua for the fully automatic speed control via 4-pin fan strips and has a low-noise adapter that reduces the maximum speed for PWM control from 3000 to 2100 U / min reduced. Its smooth-running, the SSO2 bearing and the proven premium quality from Noctua make it a first-class choice for the highest demands.
