> 3 dayI have an older AMD Phenom II, running Linux. The fan finally died. It all still works, part of my home lab. Noctua 80mm fan was almost a perfect fit. Had to drill out the aluminum just a bit. Super quiet.

> 3 dayYes, it is a tiny beast. Installed on a side panel directly above my Ryzen 1600 and it dropped 5 degrees while idle and 8 under load using the Wraith Spire. Mostly quiet operation. Construction feels solid.

> 3 dayThe fan definitely accomplishes the job for my Syber Vapor E-Gaming PC, although the screws it came with were completely useless and I had to use the heatsink that was already presently in my fan that I was replacing. In fact, that was the most challenging issue as I had to use my own screws which didnt look pretty and resulted in having to break the edges of my previous fan just to use those screws, but got the job done.

> 3 dayNoctua is known for their low volume and high airflow, and now I see why. Great fans.

> 3 dayI put these in the back wall of a 4U Supermicro 846 chassis and they are quieter at full tilt than the stock fans ramped down. To make up for the lack of air flow I have three 140mm Noctua industrial fans installed on the front. I can now sit three feet away and not need ear plugs. These fans are known as the best for a reason.

> 3 dayEste pequeño ventilador de 8cm es perfecto para esos gabinetes que lo requieren, nunca me habia tocado usar uno siempre los de 12 o 14cm pero esta vez para dos proyecto que usan un chassis mas pequeño me toco buscar este modelo y genial que sea PWM. Como siempre Noctua y sin mas que acotar cumple lo prometido, calidad, bajo ruido y simple de instalar.

> 3 day0 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.
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.
