> 3 dayI have a desktop mini fridge that had a 12v fan in it that was obnoxiously loud. So I swapped it with this one, which required splicing and soldering. This works great, its completely silent now, and still cools just as well. Love it!

> 3 dayLoved their care they put into packaging and attention to detail. Ordered 2x 80mm fan for my mini itx and it works wonderfully. silent and keeps my case cool as exhaust fans.

> 3 dayFeels well made, delivers on how quiet it is. Could probably cost half as much if the extra 3 cables I dont need and fancy packaging were optional.

Greater than one weekUse it to cool my nvme ssd on the back side of the motherboard. Even at full speed it is still very quiet.

> 3 dayDoesnt pull a ton of air, even at max speed, but its an 80mm fan. The rubber corners tend to slip and slide all over the place when installing them, but its a one-time inconvenience I can deal with.

Greater than one weekThe fan itself is somewhat quieter than the previous fan (front case fan), but it changes speed erratically, resembling a car motor sound. No apparent change in case temperature. The anti-vibration silicon feet that the fan sits on dont snap into the holes (the instructions dont give any indication), so the fan is kind of suspended mid-case. I hope it doesnt fall off and break itself.

> 3 dayThese are one of the ugliest consumer products that people just LOVE. So when I had to replace some completely hidden fans deep inside my parents prebuilt, I got one of these. The construction on these is just amazing. I mean, Im blown away. Its like fan art. And things run the risk of looking gimmicky, but then you read the reviews and it seems that the construction detail actually does convert to performance. So, I get it now. Ill never place one where it can be seen. But Ill try to hide as many as I can.
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.
