> 3 dayNice quiet fan. Does not move much air.

> 3 dayAs quiet as they come. The colors are... well, Noctua colors. But Id trade looks for quiet any day in a fan.

> 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.

Greater than one weekthese fans are more quiet than the hard drives, I now need to figure out how to configure spindown on the drives on linux.

Greater than one weekLove these fans although they do not blow you away. They are silent and rarely spin up enough for to be heard. Great quality.

> 3 dayExcellent replacement for an OEM fan on IC-7300. Almost noiseless. Took a little work (see various websites), but worth the $, work, and time.

> 3 daySecond to none for quiet and cool, but more expensive than most.. worth it for me but some may not agree.

> 3 dayI pulled a little bit of a hack and installed this in my projector to replace its crazy loud fan. Im not certain that this fan is keeping it cool enough, but wow, its less than half the noise!
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.
