> 3 daythese fans are more quiet than the hard drives, I now need to figure out how to configure spindown on the drives on linux.

> 3 dayI have an older AMD Phenom II, running Linux. The fan finally died. It all still works, part of my home lab. Noctua 80mm fan was almost a perfect fit. Had to drill out the aluminum just a bit. Super quiet.

> 3 daysuper happy of these fans it exhaust all of the hot air from my Corsair 250D and does it without making any noise!!

Greater than one weekReplaced stock fan in our nx300d amplifier with this fan. A bit of a passion to do but the sound reduction is pretty amazing. I suspect it also moves a bit less air but am very happy with the compromise

Greater than one weekIts not quiet when its at full speed as its marked, but its ok.

> 3 dayGreat fan. Perfect for my custom build. I used it in a tight spot to feed outside air to the 3 stock fans of my 1080ti. The card has never exceeded 58 degrees C. and my hot m.2 ssd sits right under the intake of the third fan. Very very happy I am.

> 3 dayI bought two of these to replace the cheap fans in my rackmount case. Not only are these Noctua fans well engineered and designed they are dead quiet. I used the rubber mounting grommets that are shipped as an install option in lieu of the metal screws. This really helps reduce any vibration noise on the case. Noctua products are simply hard to beat.
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.
