> 24 hour(WARNING: At the time of writing, the product description is entirely wrong. It says in 3 different places: Proven NF-P12 Design + NF-P12 120mm fan + NF-P12 PWM. So, the only text out of all the information entered by Amazon that is currently correct is the title at the very top which says Noctua NF-A8 PWM Premium 80mm Fan. But, everything else references an entirely different fan. And if you happen to be reading about several different fans at the same time and scroll down this page just enough so you no longer see the title, you can very easily end up ordering what you think is an NF-P12 based on the other 3 places it mentions that. Come on Amazon, you only got the model correct in 1 place out of 4 on the page??? Your customers deserve better!)

> 24 hourSpent over 100 dollars in Noctua fans already. I put that stuff on everything... Simply the best, just buy them. They are an ugly shade of brown? When you plug them in you will understand and completely ignore this fact, I guarantee it.

> 24 hourThis review is for both the 92mm and 80mm versions of this model, 4-wire units with speed controlled by the motherboard.

> 24 hour0 complaints, I personally dont mind the color as a lot of negative reviews on here are about? (why) There is no noticeable noise, using this in a 4U rack mount CPU case.

> 24 hourDoesnt 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.

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.
