> 3 dayAlways love Noctua fans, the quietest of the fans out there as far as I know.

> 3 dayBought 2 for some extra cooling to the hard drive area of the Cooler Master HAF XB. I guess theyre working and quiet. Cant hear them over the battery backup in the same rack as the computer. Im glad the fans are on the inside of the machine and on the back of it because like every other Noctua fan, theyre ugly as sin. Came well-packaged and with multiple different connectors/extensions and mounting hardware.

> 3 dayReplaced the 80mm fan on the back of my 12 drive cage. The computer is silent again.

> 3 dayThe CPU fan which also acts as the primary fan for the whole computer in my wifes little Lenovo IdeaCenter 510S all-in-one PC was starting to make noise. I am a long time PC builder and wanted to make her computer as close to silent as possible. I hardly even look at other fan brands anymore, I usually just buy Noctua and be done with it. Yes, they cost the most, but you will never be disappointed.

> 3 dayIts a Noctua... dropped right in as a replacement for the noisy stock CPU fan. Plan to get another to replace the fan in the PSU soon.

> 3 dayThe anti vibration mounts included are too short, much shorter than all of the other mounts Ive received with other noctua fans (a lot). I cant reach under the fan and pull the end to mount it properly in my cramped case. The fans feel quality. I just dont understand why the mounts are not normally sized - now Ill probably have to buy new mounts and wait longer to finish my build. unless I can come up with a way to reach under the fan

15-06-2025Put into a 3-year-old HP Pavilion 570 desktop that had a whirring fan noise at each startup. Then I had a warning on the screen to replace the fan. Got Amazon quick delivery, installed in 15 minutes, and - voila, the silence was deafening! Well packaged product, lots of accessory cables, very good quality item. Highly recommend.

The NF-A8 is a highly optimised, premium quality quiet 80mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8. 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 2200 to 1750rpm. 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 ChannelsThe NF-A8 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 bearingThe NF-A8 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 padsIntegrated 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
|
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.
