> 3 dayI 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!

> 3 dayI used this Noctua NF-A8 PWM, Premium Quiet Fan to replace a functioning, but very loud fan. I had previously purchased a Noctua double fan unit for a CPU that was hitting Temps over 99C and it brought those Temps down to 54C - a very reasonable number. So it was so much easier to find a replacement side panel fan with the same name. With this fan my motherboard stays around 44C/CPU 48C (6 Core AMD Processor). This is important because I have computers that use folding@home software to fight a variety of diseases including COVID 19. The program is demanding so cooling is an absolute must. In the future should I need another fan - Noctua will be the brand!

> 3 dayAs usual Noctuas quality doesnt disappoint. Most 80mm are just simply too weak. The NF-A8 moves air similar to a 120mm fan and its probably because of the max 2200 rpm speed, but its quiet at high speeds!

> 3 dayIm 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).

> 3 dayAs quiet as they come. The colors are... well, Noctua colors. But Id trade looks for quiet any day in a fan.

> 3 dayThey 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.
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.
