> 3 dayThese are one of the ugliest consumer products that people just LOVE. So when I had to replace some completely hidden fans deep inside my parents prebuilt, I got one of these. The construction on these is just amazing. I mean, Im blown away. Its like fan art. And things run the risk of looking gimmicky, but then you read the reviews and it seems that the construction detail actually does convert to performance. So, I get it now. Ill never place one where it can be seen. But Ill try to hide as many as I can.

> 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 dayI would upgrade the Easy to install rating from a two star to 4 star if they included one or two spare vibration silicone mounting pegs that can start to brake if you pull too hard. Its hard to fully snap fans on which a bear when mounting them to a case.

> 3 dayHave this in an older Antec case Thats has space for 1 120mm fan and 1 80mm fan. The stuck 80mm was very loud and had some funky LEDs. Replaced it with one of these and added a second to the 5.25 inch bays. Super quiet and moves a good amount of air. Little bit pricy but not too bad

> 3 dayThese are great fans - very reliable, quiet, good.

> 3 dayAbsolutely silent when using the noise reduction adapter. This does reduce the airflow and increase temperatures slightly. This comes with rubber screw replacements, but they often break, just use the screws.

> 3 dayMy case only had one slot for an 80mm fan in the back and I am not disappointed in this fan it moves a lot of air even using the low noise adapter. It is more on the expensive side for fans buy trust me its worth it.

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.
