> 24 hourMost 80mm fans are noisy, these, like other fans from Noctua, these are whisper quiet.

> 24 hourA 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.

> 24 hourThese fans are much quieter than stock fans and provide good air flow as well.

> 24 hourGood fans, not sure if they are worth the hype they receive, but I wanted the best and thats what these are supposed to be.

> 24 hourThe fans are perfect for small rack mount servers.

> 24 hourIts difficult to imagine a fan being more premium.

> 24 hoursuper happy of these fans it exhaust all of the hot air from my Corsair 250D and does it without making any noise!!

> 24 hourMy 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.

> 24 hourLoved their care they put into packaging and attention to detail. Ordered 2x 80mm fan for my mini itx and it works wonderfully. silent and keeps my case cool as exhaust fans.
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.
