Greater than one weekReplaced the fan in an Icom IC-7300 HF radio. Was easy to do (thank you, YouTube) and works quite the treat. I keep an eye on my radios temp while sending. But so far, even though it moves less CFM, been well pleased.

> 3 dayAt first my PC sounded like it was ready for takeoff and now I can barely hear it. It keeps my PC cooled and its not noisy. 10/10 would recommend

> 3 dayA bit more expensive than most fans of the same size, but they are rather quiet and will move air effectively. I have a pair in the back of a rack-mount computer case and it does the job well, quietly.

Greater than one weekEssential 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.

> 3 dayGreat fan, and very quiet. I am using this as a replacement for a heatsink fan and it is whisper quiet while keeping things well cooled. One note, be careful if trying to use this with Dell (and possibly other OEMs), as Dell uses a thin 5 pin Motherboard connector that you will have to buy an adapter to get this to work with.

> 3 dayI put these in the back wall of a 4U Supermicro 846 chassis and they are quieter at full tilt than the stock fans ramped down. To make up for the lack of air flow I have three 140mm Noctua industrial fans installed on the front. I can now sit three feet away and not need ear plugs. These fans are known as the best for a reason.

> 3 dayAs 70s/80s as they look with the sexy brown and beige color scheme, these puppies are incredibly high quality, incredibly silent, and move some air. Highly recommended. The rubber bits at the corner to help dampen any vibrations are a thoughtful touch.

Greater than one weekVery quiet fans. Bought two of these to just to provide a little circulation in the bottom chamber of my Cooler Master HAF XB EVO (yeah...probably overkill since most of the heat generating components are in the upper chamber....but figured what the heck since I was populating the other fans with Noctuas). Anyway, when I first powered the system on I had to visually inspect the fans to make sure they were spinning because they were so quiet. How cool is that... (horrible pun)

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.
