> 3 dayYes, it is a tiny beast. Installed on a side panel directly above my Ryzen 1600 and it dropped 5 degrees while idle and 8 under load using the Wraith Spire. Mostly quiet operation. Construction feels solid.

Greater than one weekOf three fans that I compared, this was the noisiest and least efficient (more current and less air) than the other two. It did come with several cables and mounting accessories that I didnt use.

> 3 dayI ordered a new fan, but it is clearly a used product, look at the pictures. Dont buy here it can happen to you as like me. First time that happend to me in Amazon. Buy from another seller. At least the fan works and it is silent.

> 3 dayLove these fans although they do not blow you away. They are silent and rarely spin up enough for to be heard. Great quality.

Greater than one weekThese 80mm fans have to be the quietest 80mms I have ever used. You could put these in an old PC power supply from the 90s and the computer would become immediately silent, especially if you use the low noise adapter. Compared to the A12, the A8 is a whisper.

> 3 dayI used this Noctua NF-A8 PWM, Premium Quiet Fan to replace a functioning, but very loud fan. I had previously purchased a Noctua double fan unit for a CPU that was hitting Temps over 99C and it brought those Temps down to 54C - a very reasonable number. So it was so much easier to find a replacement side panel fan with the same name. With this fan my motherboard stays around 44C/CPU 48C (6 Core AMD Processor). This is important because I have computers that use folding@home software to fight a variety of diseases including COVID 19. The program is demanding so cooling is an absolute must. In the future should I need another fan - Noctua will be the brand!

> 3 dayVery 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.)
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.
