> 3 dayThese 80mm fans have to be the quietest 80mms I have ever used. You could put these in an old PC power supply from the 90s and the computer would become immediately silent, especially if you use the low noise adapter. Compared to the A12, the A8 is a whisper.

> 3 dayVery well made and includes several different cable lengths. Just doesnt plug into my DELL MB fan header. My oversight. I have had twp DELL PCs and know most DELL PCs use proprietary components. The thing that really torques my hind side is that the ONLY adaptor I have found to enable me to use the Noctua case fan costs as much as I paid for the fan. If I want to use the Noctua fan,I am going to have to find an adaptor, and I can tell you they are scarce. Bah Humbug DELL

> 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 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 dayBought 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.

> 3 dayQuieter than I expected, even at full power.

> 3 dayCan you get past the ugly brown and tan color? Good. Because these fans are whisper quiet and provide a great amount of airflow. I added these to my Rosewill LSV-4412 Hot swap case because the fans included with that case were sub-par. However, these fans brought my case temps down ~5C and they dont add any noticeable noise to my server case. Highly recommend Noctua to anyone who wants professional fans that work great...despite the color
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.
