> 3 dayThe compactness and power is good and the price is fair but maybe a little inflated. Ive heard their regional quality can be wanting too so I hope noctua does a better job with that. This fan, however, is pretty quiet as I dont have it in a 4 pin slot.

> 3 dayFor 80mm fans, they are still very quiet...

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

> 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

> 3 daysuper happy of these fans it exhaust all of the hot air from my Corsair 250D and does it without making any noise!!

> 3 dayExcellent fan!! Works flawlessly, although that was to be expected with noctuas quality. Fan is silent at low rpms, and not too loud when ramped up.

> 3 dayThe fan definitely accomplishes the job for my Syber Vapor E-Gaming PC, although the screws it came with were completely useless and I had to use the heatsink that was already presently in my fan that I was replacing. In fact, that was the most challenging issue as I had to use my own screws which didnt look pretty and resulted in having to break the edges of my previous fan just to use those screws, but got the job done.

> 3 dayEven they do the job well and are very quiet, they are fugly and I had to swap them out right after i installed them.
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.
