> 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 dayUse it to cool my nvme ssd on the back side of the motherboard. Even at full speed it is still very quiet.

> 3 dayI put these in the back wall of a 4U Supermicro 846 chassis and they are quieter at full tilt than the stock fans ramped down. To make up for the lack of air flow I have three 140mm Noctua industrial fans installed on the front. I can now sit three feet away and not need ear plugs. These fans are known as the best for a reason.

09-06-2025Silent Running. Got this fan for my old HP. Dropped right in. No problem. Used the reduced rpm cable included. Soooo quiet I catch myself grabbing my flashlight to see if its running....5 star !!

> 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 dayNot loud at all. Barely even hear it.

> 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.

> 3 dayPut 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.
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.
