Greater than one weekEverything as advertised, extremely quiet.

> 3 dayGreat fan that came with a lot of extras (stabilizers, rubber feet to decrease noise, and multiple options for connecting it). Only issue is that it is about 2mm bigger between the holes than it says. This probably is not an issue for most (as this fits a standard configuration in a computer) but it did not work for my purposes (replacing a noisy fan in my aquarium hood). 4 Stars because of the misfit, and because I had to order this twice (the first time it never showed up, but amazon refunded my money so it was all good).

> 3 dayPurchased two of these fans for use in a Silverstone GD09B HTPC chassis. Was worried that running two 80mm fans in here 1) wouldnt fit, and 2) would be too loud. Am happy to report that these fit side by side easily in the rear exhaust area on the Silverstone case, and that they are not audible using the standard profile from my motherboards pwm header.

> 3 dayUsed this in my NAS and PC build. Theyre quiet and move a decent amount of air. My complaint is the color. Brown?! Really. And price is a little high. worth it, that would be a personal choice.

> 3 dayI would upgrade the Easy to install rating from a two star to 4 star if they included one or two spare vibration silicone mounting pegs that can start to brake if you pull too hard. Its hard to fully snap fans on which a bear when mounting them to a case.

> 3 dayNice and quiet at full speed just like a Noctue should be. Got 2 for rear exhaust on a Lian Li case.

> 3 dayTested them out of the box, very quite. Have not installed them in their final location yet. Plan to use them with a thermally controlled PWM control board to cool condenser in my motor home refrigerator.
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.
