Brand: Noctua
MPN: Noctua NF-A9 PWM

Noctua NF-A9 PWM Premium Quiet Fan 4-Pin (92mm Brown)
Product Description

The NF-A9 is a highly optimised premium quality quiet 92mm fan. Featuring Noctua’s 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 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.

^{AAO frame}

Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures both of which further refine the fan's performance/noise efficiency.

The NF-A9 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.

^{SSO2 bearing}

The NF-A9 features the further optimised second generation of Noctua's renowned time-tested SSO bearing. With SSO2 the rear magnet is placed closer to the axis to provide even better stabilisation precision and durability.

^{Integrated anti-vibration pads}

Integrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.

^{Scope of delivery}

• Low-Noise Adaptor (L.N.A.)
