> 3 dayPut into a 3-year-old HP Pavilion 570 desktop that had a whirring fan noise at each startup. Then I had a warning on the screen to replace the fan. Got Amazon quick delivery, installed in 15 minutes, and - voila, the silence was deafening! Well packaged product, lots of accessory cables, very good quality item. Highly recommend.

> 3 dayThey may seem pricy. You might not like the color, but these are hands down the best fans money can buy. When they say ultra quiet, they mean it. I put them in an old NAS that was so loud that you could hardly stand to be in the room with it. Now it’s so quiet I forget it’s on, and it even runs cooler than before.

> 3 dayI replaced both my CPU fan with an 80mm and my case fan with a 92mm version of the Noctua fans. The are very quiet and seem well made. Box included 3 additional cables, screws and rubber mounts in case I needed to use them... Didnt need for my install, but nice touch! Very happy and recommend them!

> 3 dayGreat fan, replaced the stock 80mm that came on my CPU heatsink. Amazing difference in noise levels and moves plenty of air when the system asks it to. Everyone who is into PCs knows what Noctua fans are, and they are worth their price and their colors to have the best thermal performance for your PC.

> 3 dayBought 5 of these for Home server, can’t even tell it’s on with how silent it is.
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.
