> 24 hourThe compactness and power is good and the price is fair but maybe a little inflated. Ive heard their regional quality can be wanting too so I hope noctua does a better job with that. This fan, however, is pretty quiet as I dont have it in a 4 pin slot.

> 24 hourProduct arrived within 3 day . Very professional package all the different wiring choices and all necessary hardware for the installation inside the kit. It looks like very good product and very good warranty. Just installed it. Very easy installation , time will show how it will perform . So far satisfied with purchase!

> 24 hourThese are as quite as they are ugly and they are really quite! None of the provided mounting hardware worked for my application so be aware you might have to hit the parts bin to make these work.

> 24 hourUsed 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.

> 24 hourI bought a 92mm and 80mm Noctua case fan and so far it really made a difference in terms of noise reduction. I switch Noctua fan with my old one and i thought my PC died on start up because of the sudden drop of noise after 1-2 second of starting up. I can actually hear what is happening inside my PC now due to the fan being almost dead silent.

> 24 hourIm using it as a OEM fan replacement on top of the OEM Intel heatsink for a i7-7700 CPU. It made a 5 to 8 degree Farenheit difference. Thats better than nothing. Before anyone says, just replace the stock heatsink with an aftermarket upgrade you big dork!, LOL..., I tried that already.

> 24 hourI had a weird case that I needed to get these for to replace some noisy stock fans, the extra kit you get with this fan is amazing. You get a y splitter, an extension cable, and a low voltage (silent mode) adapter. And on top of that it is a Noctua fan and the hype surrounding these fans is real.
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.
