> 3 dayEssential component to a recent ITX build of mine (Fractal Ridge). You get what you pay for with Noctua - in this case, that means okay/good CFM at lower speeds while also yielding extremely quiet noise levels.

Greater than one weekVery low noise fans. The quiet adapter it comes with is really good. I have 5 nested 4 pin PWM fans plugged into the little low noise adapter cable. now all fans are running at 600~ rpm (what i needed). Now I can sleep at night without turning off my server. (This could have been done through BIOS or a fan controller. But, it is still very neat.)

> 3 dayI replaced some older Lian Li case fans with a few of these Noctuas and I could not be happier!

> 3 dayNot as powerful as I thought it be based on other Noctua fans, but eh, it is small...

> 3 dayThese are the best fans in the world for a reason... and even though they are the most hideous PC parts that Ive ever seen, I dont think that Ill ever go back.

> 3 dayI recently started hearing a fan whine coming from my cpu cooler fan. Being since its a old Dell xps 8700 with a i7 4790. I didnt want to buy a cpu cooler for it since its never given me a heat issue. I was already planning to clean out the old thermal paste on it and decided to purchase this. I had already swapped out the rear fan about 2 years back with a noctua 92mm fan to help with the noise and improve thermals. Happy to say you dont hear it at all and noticing my cpu idling a little bit cooler with the stock heatsink attached.
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.
