> 24 hourReplaced 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.

> 24 hourIts fine for a fan, but too overpriced in my opinion

> 24 hourThese are as quite as they are ugly and they are really quite! None of the provided mounting hardware worked for my application so be aware you might have to hit the parts bin to make these work.

> 24 hourNoctua, I love you. You made a Sandy Bridge Xeon run like its on ice, even with the stock heat sink.

> 24 hourThese fans may not be the cheapest, but they are extremely quiet and have a reputation for reliability. Comes with an array of cables and some rubber mounting pegs.

> 24 hourA good replacement of OEM fans, if you want non-vibrating and quiet 80mm fan. The only con is the color palette, but, as its sort of Noctuas signature, theres nothing you can do about it.
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.
