> 3 dayUsed these fans to replace the factory fans in my Inuke 6000dsp amp. These fans are so much more quieter.

04-11-2024these fans are more quiet than the hard drives, I now need to figure out how to configure spindown on the drives on linux.

> 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.)

> 3 dayPurchased this fan to replace a noisy stock fan. I was very impressed by the results. The fan is completely inaudible over other case noises, and judging by my temperatures, is still moving a substantial amount of air over the components. Highly recommend for anyone who is looking for a Quiet fan with a capital Q.

> 3 dayThey may seem pricy. You might not like the color, but these are hands down the best fans money can buy. When they say ultra quiet, they mean it. I put them in an old NAS that was so loud that you could hardly stand to be in the room with it. Now it’s so quiet I forget it’s on, and it even runs cooler than before.

> 3 dayI do a lot of custom builds whether it’s small electronics, emulator boxes, 3-D, print builds, etc. this is the only brand fan company I will use. Rocksolid great cooling you don’t even hear them on.

Greater than one weekIf you have to install two of these packed together all the rubber noise reduction will make this tricky. I had to put the screws on and angle to get the second fan in my case.
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.
