> 24 hourIm using 2 of these fans in my front to pull cool air into the case and they are doing an excellent job keeping the airflow moving and the internal components (especially my GFX) cool. So far Im a new but HUGE fan of Noctua and believe they are the only company Ill be using for future cooling purchases. All of the recent fans (cpu cooler, 120mm, and 80mm) have been through Noctua for the efficiency of airflow and low noise they provided (none are using the provided low noise adapters as I havent seen the need to use them).

> 24 hourGreat 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.

> 24 hourThese are easily the best 80mm fans you can buy. I bought a couple of them to cool a 750Ti which I removed the stock fans and fan shroud. They are literally silent. They are impossible to hear if they are turned down using the motherboard. I even replaced my standard light bulbs in my room with LED ones because my computer was so silent I could hear them humming and that was starting to drive me crazy... but Im pretty OCD about things like this.

> 24 hourPurchased two of these fans for use in a Silverstone GD09B HTPC chassis. Was worried that running two 80mm fans in here 1) wouldnt fit, and 2) would be too loud. Am happy to report that these fit side by side easily in the rear exhaust area on the Silverstone case, and that they are not audible using the standard profile from my motherboards pwm header.

> 24 hourFor 80mm fans, they are still very quiet...

> 24 hourThe 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.

> 24 hourWhat can I say, its Noctua, the finest and most reputable PC fan manufacturer there is.

> 24 hourI do a lot of audio and video recording in my office and have noticed a computer hum in some recordings. After doing some research I found out about these fans which as supposed to reduce noise. I pulled my computer apart to find out what I needed and ordered the replacement fans. They came in two days and I installed them. They looked good and fit perfectly, but I have been disappointed with the results. The noise isnt any better than it was with the original factory fans. I went through all that work for no change. So Im going to have to pursue a different and more drastic sound dampening approach. I wouldnt waste your time with these so called silent fans!

> 24 hourSecond to none for quiet and cool, but more expensive than most.. worth it for me but some may not agree.
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.
