> 3 dayNot loud at all. Barely even hear it.

Greater than one weekI pulled a little bit of a hack and installed this in my projector to replace its crazy loud fan. Im not certain that this fan is keeping it cool enough, but wow, its less than half the noise!

22-11-2024I purchased these to replace some stock fans. They’re super quite and are easy to install. These are by far my fan of choice

> 3 dayBought 2 for some extra cooling to the hard drive area of the Cooler Master HAF XB. I guess theyre working and quiet. Cant hear them over the battery backup in the same rack as the computer. Im glad the fans are on the inside of the machine and on the back of it because like every other Noctua fan, theyre ugly as sin. Came well-packaged and with multiple different connectors/extensions and mounting hardware.

> 3 dayReplaced 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 dayVery Quiet, perfect fit. For a system that isnt seen the color doesnt matter. Best fans on the market.

> 3 dayAhhh, quiet. Replaced the stock fans on my radio & power supply and no more background fan noise.

Greater than one weekI used this fan to replace the stock fan in my Icom IC-7300, which was quite loud during transmit. The Noctura fan is essentially silent. I cant hear it at all. If youre looking for a quiet fan, look no more, this is the one.

Greater than one weekIve used these for decades and they simply work, every time, in silence.

> 3 dayUsing them in my TT mini cube T1 case. They move a lot of air and keep the motherboards voltage regulators nice and cool. They are super quiet, even at full speed.
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.
