> 3 dayUsing this in a MSI Z170A M7 / i5-6600K build. You have to set the Smart Fan controls in bios first (didnt see my boot ssd otherwise) and then it is whisper quiet. I also have the NH-L12 low profile CPU cooler. when hooked up and the NF-P12 case fan. If you let the motherboard control these fans, you have a hard time knowing they are on. CPU and case temps are in the blue, even during video conversion. Love these fans and you cant go wrong with Noctua!

> 3 dayThis fan is amazing. I needed a small fan to fit in a side panel of my silverstone sg13 and originally had a be quiet pure wings in there. The be quiet fan made a horrible whining noise that drove me nuts. I put this notuca fan in (with the noise reduction cable that comes with it because it is running on a fan splitter) and it is dead silent. If you need quiet, this is the fan to get.

> 3 dayWow. What a difference. I replaced a Silenx Ixtrema Pro IXP-54-14 that had seized up. The packaging reminds me of a Nest or iPhone. Build quality seems to be very good, the power cable was a little short but an extension cable is included (along with a 3 to 4 pin adapter and a low-noise cable that makes the fan spin slower). Took five minutes to swap out the fans and it is very silent. Better quality than I expected. A pleasant surprise.

> 3 dayI hacked my studio light (godox SL-60w) and swapped the stock fan out with this fan, and it turned a previously noisy mess into a silent whisper. I cant even hear it unless Im in a dead quiet room and less than 1 foot away.

> 3 dayVery quiet. I use it to cool some hdd. It does not provide a lot of air flow, but it is very quiet.
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 ULN version provides super-slow 1400/1100rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation. 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.
