> 3 dayAs quiet as they come. The colors are... well, Noctua colors. But Id trade looks for quiet any day in a fan.

> 3 daywould not run at POST and boot up until computer called for high fan speed. BIOS fan test failed. Fan test expected speed of 2600RPM; actual results of 4 test reported 1000RPM each test.

> 3 dayBest fan manufacturer Ive found. Ive experienced fan failures and excessively noisy fans over the years, but never from a Noctua. I use them in all my computer cases anywhere a fan will fit, and my first Noctua CPU fan/heat sink combo (NH-C14 on a 1st generation I7 processor) is phenomenal. A perfect compliment for an SSD, you may have to look twice to see if the PC is on!

> 3 dayyou can tell its nice cause the box it comes in is heavier than the fan itself

> 3 dayI bought a set of these to put into my Thermaltake Core V1 build. They are extremely quiet fans. The only thing that I honestly dont like about them is the look. That brown color really isnt that good to look at. I probably will end up swapping them out for some Chromax one, once they make them or I might go to a different brand all together. The fans themselves are great, just the overall look, not the greatest.

> 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.

Greater than one weekWell the fan is amazing queit despite its high rpms i originally purchased it to replace an old heatsink fan but i was off on the dimensions my fault but otherwise i still use this fan in all its glory o.O

> 3 dayI bought this to replace the original fan in my Xaminer 64tb - This is the only approved replacement fan for Xaminer (as of 9/8/22). The original got progressively noisier over a period of several months until it failed completely.

Greater than one weekI used this fan to replace the stock fan in my Icom IC-7300, which was quite loud during transmit. The Noctura fan is essentially silent. I cant hear it at all. If youre looking for a quiet fan, look no more, this is the one.
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.
