Noctua NF-A9 PWM 12V 2000RPM 92mm Premium Quality Fan

- Replaces the Noctua NF-B9 PWM 92mm Cooling Fan

Noctua's new 92mm fans have been updated to feature their innovative technology. The NF-A9 PWM offers automatic fan speed control when connected to a PWM fan header on the motherboard.


  1. Sound-optimised blade geometry and profile (Flow Acceleration Channels)
  2. Self-stabilising oil-pressure bearing (SSO2 Bearing)
  3. <17 dB(A) minimum noise with supplied L.N.A.
  4. 46.4 CFM maximum airflow
  5. Includes 4 Vibration-Compensators
  6. Six years warranty

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-Resistor 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.

Customer Reviews

Quiet and efficient


Have this in a small PC build (Streacom F7CWS case) and together with a Noctua CPU cooler, it is doing a great job of keeping everything in the box cool including an i7 8700 with very little noise.

Alienware Aurora Much Quieter


Replaced all 5 fans (chipset, RAM, HDD, PCI & PSU) in my 2010 Alienware Aurora R1 with Noctua units. Well worth the money. Machine is practically silent now and internal temps are down by at least 10 degrees C.
