> 3 dayTested them out of the box, very quite. Have not installed them in their final location yet. Plan to use them with a thermally controlled PWM control board to cool condenser in my motor home refrigerator.

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

> 3 dayExcellent replacement for an OEM fan on IC-7300. Almost noiseless. Took a little work (see various websites), but worth the $, work, and time.

> 3 dayIts a Noctua fan. The name (and color) speaks for itself. Quiet, efficient, and gets the job done. Enough said!

> 3 dayThese fans are very well made. They are extremely quiet and durable. I installed them into my 4U server that contains 24 hard drive bays. After switching the fans that came with the case for these the was no more hum. Just extreme quietness. I would recommend these fans to anyone looking for a great quality made fan.

> 3 dayThere’s a saying “you get what you paid for” and that’s the noctua fans. Noctua fans are the most expensive fans I’ve seen when I was building my $5000 pc. It’s crazy how quiet they can become. The noctua fans are considered ugly because it’s brown, but I actually like the beige and brown color. It’s a nice touch to any classic pc.

> 3 dayIts a Noctua... dropped right in as a replacement for the noisy stock CPU fan. Plan to get another to replace the fan in the PSU soon.
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.
