> 3 dayA Great running quite fan with a 4pin hookup to the power fan link on the computer motherboard- Speed regulates depending on the internal temperature of the processor

> 3 dayThe fan I was delivered had no damage to the box, yet the fan was not as quiet as the factory cooling fan on my old dell xps8700.

> 3 dayExcellent replacement for an OEM fan on IC-7300. Almost noiseless. Took a little work (see various websites), but worth the $, work, and time.

> 3 dayI used this fan to replace the stock fan in my Icom IC-7300, which was quite loud during transmit. The Noctura fan is essentially silent. I cant hear it at all. If youre looking for a quiet fan, look no more, this is the one.

> 3 dayGreat fan that came with a lot of extras (stabilizers, rubber feet to decrease noise, and multiple options for connecting it). Only issue is that it is about 2mm bigger between the holes than it says. This probably is not an issue for most (as this fits a standard configuration in a computer) but it did not work for my purposes (replacing a noisy fan in my aquarium hood). 4 Stars because of the misfit, and because I had to order this twice (the first time it never showed up, but amazon refunded my money so it was all good).

Greater than one weekI 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.

> 3 dayEssential component to a recent ITX build of mine (Fractal Ridge). You get what you pay for with Noctua - in this case, that means okay/good CFM at lower speeds while also yielding extremely quiet noise levels.
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.
