> 24 hourEssential 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.

> 24 hourSilent Running. Got this fan for my old HP. Dropped right in. No problem. Used the reduced rpm cable included. Soooo quiet I catch myself grabbing my flashlight to see if its running....5 star !!

> 24 hourReplaced a noisy Cooler Master fan that came with my HP computer with this one. What do I hear now? Absolutely nothing.

> 24 hourThey may seem pricy. You might not like the color, but these are hands down the best fans money can buy. When they say ultra quiet, they mean it. I put them in an old NAS that was so loud that you could hardly stand to be in the room with it. Now it’s so quiet I forget it’s on, and it even runs cooler than before.

> 24 hourAfter reading the reviews I decided to purchase a few Noctua fans for my new PC builds. I was not disappointed. Ive been building PCs for over 20 years and these are by far the nicest fans I have ever installed. They are ugly IMO but if you can get over the color combo you will not regret purchasing these fans. They are packaged better than any other fan and they are dead quiet. Highly recommend!

> 24 hourMy amp sounded like a Vacumm..now is super silent. Best mod ever to calm your noisy devices. I use them in my HTPC build as well.

> 24 hourExcellent fan!! Works flawlessly, although that was to be expected with noctuas quality. Fan is silent at low rpms, and not too loud when ramped up.

> 24 hourThis fan is performing as expected; it is virtually silent. Lots of cheaper options out there, but you get what you pay. I have purchased several Noctua fans and cpu coolers, and am happy with all of them. No failures or other issue to date, and they are all 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.
