> 3 dayMy case only had one slot for an 80mm fan in the back and I am not disappointed in this fan it moves a lot of air even using the low noise adapter. It is more on the expensive side for fans buy trust me its worth it.

> 3 dayThis is the quietest fan Ive ever used - dead silent, in fact; however, the reason its so quiet is that it doesnt spin. When the computer starts, the fan spins for less than a second then does nothing, no matter how warm the computer gets. Ive tried several other fans on the same MB header, all work. The other fans are noisier than Id like, which is why I ordered this one. If, however, the tradeoff for a quieter computer is overheating, Ill endure the noise.

19-12-2024Using 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.

> 3 dayGood fans, not sure if they are worth the hype they receive, but I wanted the best and thats what these are supposed to be.

Greater than one weekExcellent fan!! Works flawlessly, although that was to be expected with noctuas quality. Fan is silent at low rpms, and not too loud when ramped up.

Greater than one weekthese fans are more quiet than the hard drives, I now need to figure out how to configure spindown on the drives on linux.

> 3 dayIncredibly quiet at max RPM.

> 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 dayAbsolutely silent when using the noise reduction adapter. This does reduce the airflow and increase temperatures slightly. This comes with rubber screw replacements, but they often break, just use the screws.
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.
