> 24 hourNoctua fans are the best for noise these are all I buy when I need a fan

> 24 hourGreat fan, and very quiet. I am using this as a replacement for a heatsink fan and it is whisper quiet while keeping things well cooled. One note, be careful if trying to use this with Dell (and possibly other OEMs), as Dell uses a thin 5 pin Motherboard connector that you will have to buy an adapter to get this to work with.

> 24 hourJust a great set of fans that really do the job. PWM fans can be controlled with the motherboard and have near silent operation at maximum power. The Fans are just built great and keep the system more than cool. I would highly recommend them. They come with splitters so you can add more than one of these to one fan header. Just be aware the splitter only measures the RPM of one fan and inputs voltage into both.

> 24 hourVery quite and reliable. It has been running non stop for the last 150 days.

> 24 hourI got this fan as a replacement for a hard drive enclosure. The fan is a bit wider than the standard, but this is still by far the best fan you can get.

> 24 hourTo replace faulty CPU fans.

> 24 hourI forgot I had these. Seriously... They were so quiet I forgot I bought these/they existed at all. It moves a ton of air and couldnt be happier! :D

> 24 hourGreat fan real quite beats the stock fans engine turbines and its not even running hot and so loud. Glad I bought this I can enjoy my streaming.

> 24 hourBought 2 for some extra cooling to the hard drive area of the Cooler Master HAF XB. I guess theyre working and quiet. Cant hear them over the battery backup in the same rack as the computer. Im glad the fans are on the inside of the machine and on the back of it because like every other Noctua fan, theyre ugly as sin. Came well-packaged and with multiple different connectors/extensions and mounting hardware.
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.
