> 24 hourThese 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.

> 24 hourI bought a 92mm and 80mm Noctua case fan and so far it really made a difference in terms of noise reduction. I switch Noctua fan with my old one and i thought my PC died on start up because of the sudden drop of noise after 1-2 second of starting up. I can actually hear what is happening inside my PC now due to the fan being almost dead silent.

> 24 hourits so quiet its shocking not to hear any fan case noise when the PC is on, I thought it wasnt running but looked at the fans with a flashlight, and they spin, but are silent, good quality, really improves PC time with a quiet background

> 24 hourIt blows low rpm whine around 1100rpm

> 24 hourThese 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.
