> 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 dayIm using it as a OEM fan replacement on top of the OEM Intel heatsink for a i7-7700 CPU. It made a 5 to 8 degree Farenheit difference. Thats better than nothing. Before anyone says, just replace the stock heatsink with an aftermarket upgrade you big dork!, LOL..., I tried that already.

> 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.

Greater than one weekGood air flow but a little loud at full rpm. Speed control and rpm feed back to BIOS.

> 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 dayThis is a really great fan. Its hard to find a quality fan at 80mm. At this size, the fan either pumps a good amount of air but is loud, or is quiet, but ineffective.
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.
