> 24 hourwould not run at POST and boot up until computer called for high fan speed. BIOS fan test failed. Fan test expected speed of 2600RPM; actual results of 4 test reported 1000RPM each test.

> 24 hourI had a bit of a nerve-wracking experience installing it -mostly due to the high stakes (it is my cpu, after all!) and lack of experience. But everything I needed was there and since installing it Ive largely forgotten its even there.

> 24 hourAs 70s/80s as they look with the sexy brown and beige color scheme, these puppies are incredibly high quality, incredibly silent, and move some air. Highly recommended. The rubber bits at the corner to help dampen any vibrations are a thoughtful touch.

> 24 hourThey 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.

> 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 hourMost 80mm fans are noisy, these, like other fans from Noctua, these are whisper quiet.

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.
