> 3 dayThese fans are very well made. They are extremely quiet and durable. I installed them into my 4U server that contains 24 hard drive bays. After switching the fans that came with the case for these the was no more hum. Just extreme quietness. I would recommend these fans to anyone looking for a great quality made fan.

> 3 dayI recently started hearing a fan whine coming from my cpu cooler fan. Being since its a old Dell xps 8700 with a i7 4790. I didnt want to buy a cpu cooler for it since its never given me a heat issue. I was already planning to clean out the old thermal paste on it and decided to purchase this. I had already swapped out the rear fan about 2 years back with a noctua 92mm fan to help with the noise and improve thermals. Happy to say you dont hear it at all and noticing my cpu idling a little bit cooler with the stock heatsink attached.

> 3 dayUsed these fans to replace the factory fans in my Inuke 6000dsp amp. These fans are so much more quieter.

> 3 dayI have a desktop mini fridge that had a 12v fan in it that was obnoxiously loud. So I swapped it with this one, which required splicing and soldering. This works great, its completely silent now, and still cools just as well. Love it!

> 3 dayMy old case fan was getting noisy so I decided to use this Noctua to replace it. I used the rubber pull-through mounts supplied with the fan. As well as I can tell, its nearly silent and the Gigabyte app that controls temperature and fans for my motherboard and CPU shows everything is staying cool.

> 3 dayIts a Noctua fan. The name (and color) speaks for itself. Quiet, efficient, and gets the job done. Enough said!

17-11-2024Good air flow but a little loud at full rpm. Speed control and rpm feed back to BIOS.
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.
