    You can always trust Noctua to have the best fit and finish in their products. Their fan line may cost a little more, but you can rely on the quality and warranty.

    This fan works well and was easy to install. Havent had any problems and run really quiet. Would recommend.

    Dell shipped the worst, loudest stock fan in my gaming XPS. It would drown out everything and I cant believe they would ship a fan that loud.

    This product is very well made and includes all the parts I would need. I used the silicone mounts to install the fan on my desktop computer, and the extension cable to reach the PWM connector on the other end of the motherboard. During the installation, I quickly realized that those silicone anti-vibration pads must be removed in order to use silicone mounts for installation. For some unknown reason I had to restart twice to have the system up and running and recognize the fan in BIOS settings. Now the fan is running smoothly and so quietly in my computer, I dont even notice its running.

    Perfect for front fans on Node 304

    My Dell PC was getting hot playing some quasi graphic intensive games. The factory fans were just not cutting it, so after reading some reviews, I picked up one of these fans and installed it. The installation, overall, was very easy. I like the fact that they give you a splitter so that you can either add it as an additional fan or use your old fan as a secondary, which is what I did. It was harder to remove the factory fan than it was to install this one.

    Awesome, just like my other Noctua fans. Silent Performer :-)

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.

Flow Acceleration Channels

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

  • NA-RC7 Low-Noise Adaptor (L.N.A)
  • NA-YC1 4-pin PWM y-cable
  • NA-EC1 30cm extension cable
  • 4x NA-AV1 anti-vibration mounts
  • Fan screws

Inner Surface Microstructures

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
