> 3 dayUsed this in my NAS and PC build. Theyre quiet and move a decent amount of air. My complaint is the color. Brown?! Really. And price is a little high. worth it, that would be a personal choice.

Greater than one weekWent from a car motor sounding PC to slight hum.

> 3 dayThey are OK but when you hook so many fans (4) to the mother board (with 750 watt power supply) some of the fans are struggling for power. Had to cut off off plugs and reattach power supply connections and then they work fine.

> 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.

12-11-2024This is the second one I have bought. Quietest I have ever bought. I needed to replace my power supply fan and it was easier to use a second one of the Noctua NF-A8 with the supplied splitter as I have no free fan headers on my MB

Greater than one weekIt is quiet and good quality. It comes with some connectors. Everything looks so pro, doesnt like other cheap PC fan.

Greater than one weekGreat and very quiet fans. I bought tow of these fans to replace older fans. While certainly more expensive I am glad I purchased these fans. They have been very quiet and came with everything I needed to install it in the way of cabling and screws for a variety of situations. Will buy this brand again!

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.
