> 3 dayWell the fan is amazing queit despite its high rpms i originally purchased it to replace an old heatsink fan but i was off on the dimensions my fault but otherwise i still use this fan in all its glory o.O

> 3 daysilent and works for my brix well!

> 3 dayA bit more expensive than most fans of the same size, but they are rather quiet and will move air effectively. I have a pair in the back of a rack-mount computer case and it does the job well, quietly.

> 3 dayIm stunned at their ability to cool a 160mm radiator.

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

> 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 dayGreat fan, and very quiet. I am using this as a replacement for a heatsink fan and it is whisper quiet while keeping things well cooled. One note, be careful if trying to use this with Dell (and possibly other OEMs), as Dell uses a thin 5 pin Motherboard connector that you will have to buy an adapter to get this to work with.

> 3 dayAt first my PC sounded like it was ready for takeoff and now I can barely hear it. It keeps my PC cooled and its not noisy. 10/10 would 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.
