> 3 dayThe fans are perfect for small rack mount servers.

> 3 dayGreat upgrade for the old fans in my PC case. Noise level cut by 90% as compared to a molecule fan from 2003. I know that’s not much to go off of but it changed my PC so much for the better, no reason not to go noctua every time.

> 3 dayVery quiet fans. Bought two of these to just to provide a little circulation in the bottom chamber of my Cooler Master HAF XB EVO (yeah...probably overkill since most of the heat generating components are in the upper chamber....but figured what the heck since I was populating the other fans with Noctuas). Anyway, when I first powered the system on I had to visually inspect the fans to make sure they were spinning because they were so quiet. How cool is that... (horrible pun)

> 3 dayGood fans, not sure if they are worth the hype they receive, but I wanted the best and thats what these are supposed to be.

> 3 dayUse it to cool my nvme ssd on the back side of the motherboard. Even at full speed it is still very quiet.

> 3 dayThese are easily the best 80mm fans you can buy. I bought a couple of them to cool a 750Ti which I removed the stock fans and fan shroud. They are literally silent. They are impossible to hear if they are turned down using the motherboard. I even replaced my standard light bulbs in my room with LED ones because my computer was so silent I could hear them humming and that was starting to drive me crazy... but Im pretty OCD about things like this.

> 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.
