Noctua NF-A9 PWM, 4-Pin Premium Cooling Fan (92mm, Brown)

The NF-A9 is a highly optimized, premium quality quiet 92mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimization) 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 Noctua’s 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 Noctua’s trusted premium quality make it an elite choice for the highest demands
