> 3 dayThese fans are much quieter than stock fans and provide good air flow as well.

I buy too much
Greater than one weekThese fans may not be the cheapest, but they are extremely quiet and have a reputation for reliability. Comes with an array of cables and some rubber mounting pegs.

> 3 dayEssential component to a recent ITX build of mine (Fractal Ridge). You get what you pay for with Noctua - in this case, that means okay/good CFM at lower speeds while also yielding extremely quiet noise levels.

> 3 dayAhhh, quiet. Replaced the stock fans on my radio & power supply and no more background fan noise.

> 3 dayIm disappointed with this fan. Its super loud. I installed it in my Dell Optiplex and its louder than my stock CPU fan, Case Fan and 120mm front case fan altogether!

> 3 dayWork quiet and good amount of air, a bit expensive than another but worth it.

> 3 day0 complaints, I personally dont mind the color as a lot of negative reviews on here are about? (why) There is no noticeable noise, using this in a 4U rack mount CPU case.

> 3 dayThese are one of the ugliest consumer products that people just LOVE. So when I had to replace some completely hidden fans deep inside my parents prebuilt, I got one of these. The construction on these is just amazing. I mean, Im blown away. Its like fan art. And things run the risk of looking gimmicky, but then you read the reviews and it seems that the construction detail actually does convert to performance. So, I get it now. Ill never place one where it can be seen. But Ill try to hide as many as I can.
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.
