> 3 dayI used this fan to blow air over a 4-HDD RAID in my desktop. It also helps draw in extra fresh air for my CPU. I mounted it to a custom 3D printed frame in the 5.25 bays of my computer case. It works well and definitely moves some air without being too loud.

> 3 dayNice and quiet at full speed just like a Noctue should be. Got 2 for rear exhaust on a Lian Li case.

Greater than one weekPut in a Honeywell fan enclosure to replace the existing 80mm which the bearings went out on. This is working as it should. I expect it being Noctua to last a while. Very low noise compared to the stock fan.

Greater than one weekThis review is for both the 92mm and 80mm versions of this model, 4-wire units with speed controlled by the motherboard.

> 3 dayMy old case fan was getting noisy so I decided to use this Noctua to replace it. I used the rubber pull-through mounts supplied with the fan. As well as I can tell, its nearly silent and the Gigabyte app that controls temperature and fans for my motherboard and CPU shows everything is staying cool.
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.
