Greater than one weekThey 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.

> 3 dayUsed this fan on my HTPC to replace my loud Dell stock fan. Works great but you also have to order the adapter cable to use on Dell computers.

> 3 dayI bought a set of these to put into my Thermaltake Core V1 build. They are extremely quiet fans. The only thing that I honestly dont like about them is the look. That brown color really isnt that good to look at. I probably will end up swapping them out for some Chromax one, once they make them or I might go to a different brand all together. The fans themselves are great, just the overall look, not the greatest.

Greater than one weekGood fans, not sure if they are worth the hype they receive, but I wanted the best and thats what these are supposed to be.

> 3 dayThe CPU fan which also acts as the primary fan for the whole computer in my wifes little Lenovo IdeaCenter 510S all-in-one PC was starting to make noise. I am a long time PC builder and wanted to make her computer as close to silent as possible. I hardly even look at other fan brands anymore, I usually just buy Noctua and be done with it. Yes, they cost the most, but you will never be disappointed.

> 3 dayI 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.
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.
