Noctua NF-A9 PWM 92x92x25mm 4-pin PWM 2000/400rpm

The NF-A9 is a highly optimised, premium quality quiet 92mm fan. Featuring Noctuas AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9 further improves the renowned quiet cooling performance of the award-winning NF-B9. The PWM version sports Noctuas custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 2000 to 1550rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctuas trusted premium quality make it an elite choice for the highest demands.
