> 3 dayGreat fan. Perfect for my custom build. I used it in a tight spot to feed outside air to the 3 stock fans of my 1080ti. The card has never exceeded 58 degrees C. and my hot m.2 ssd sits right under the intake of the third fan. Very very happy I am.

Greater than one weekReplaced a noisy Cooler Master fan that came with my HP computer with this one. What do I hear now? Absolutely nothing.

> 3 dayAdded two to my Silverstone SG12B case for exhaust. Very quiet, very good fans.

> 3 dayI had a bit of a nerve-wracking experience installing it -mostly due to the high stakes (it is my cpu, after all!) and lack of experience. But everything I needed was there and since installing it Ive largely forgotten its even there.

Greater than one weekIve used these for decades and they simply work, every time, in silence.

> 3 dayPleantly surprise to see a conservative spec on noise reduction. The Noctura fan was better than its published spec.

> 3 dayVery pretty package. Very quiet. Expensive, but nice mounting options. Doesnt blow much air, but what do you expect from a 1400 rpm fan. I took a point off because of its cost.

> 3 dayNoctua, I love you. You made a Sandy Bridge Xeon run like its on ice, even with the stock heat sink.

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.
