> 3 daysuper happy of these fans it exhaust all of the hot air from my Corsair 250D and does it without making any noise!!

> 3 dayGreat fan real quite beats the stock fans engine turbines and its not even running hot and so loud. Glad I bought this I can enjoy my streaming.

> 3 dayThis 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.

Greater than one weekI replaced some older Lian Li case fans with a few of these Noctuas and I could not be happier!

Greater than one weekdoesnt move a LOT of air, but its silent.

> 3 dayI needed an 80mm case fan for a 2U rack mount case. 80mm fans tends to be loud, but this one was definitely quieter but still pumped the air needed to cool the components. Wherever I can, I buy Noctua fans. I dont care for the color, so I would prefer they not be fans used in visible spots, and they do have a grey/black version (Redux) but its less powerful. I would buy this fan again for case needs.

> 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 got this to replace the loud slightly whiney foxconn cpu cooler in my HP Pavillion Ryzen 3600 gaming computer and it did lower the volume, and it even slightly lowered my CPU idle temps, but my cpu temps under heavy load from video rendering went from 64.5 to 74c. ( i found disabling the turbo boost brought the cpu temps under heavy load down to 55c). Too bad my case wont let me install an 80mm to 92mm fan adapter so I could install a quiet but powerful Noctua 92mm PWM case fan as my cpu fan. :( But for case fans you cant beat this fan if you value a silent computer.

> 3 dayCan’t seem to go wrong with these fans.
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.
