> 3 dayI had a weird case that I needed to get these for to replace some noisy stock fans, the extra kit you get with this fan is amazing. You get a y splitter, an extension cable, and a low voltage (silent mode) adapter. And on top of that it is a Noctua fan and the hype surrounding these fans is real.

> 3 dayI replaced a cpu fan in Thinkcentre M93p. It works, but fails POST, as lenovos motherboard does not support zero rpm mode that this fan has, giving the two beeps and cpu fan error. Or something else might be the issue, but that is why I took down one star. Other than that, it is a great fan, silent, and with good airflow.

> 3 dayFor such a small fan, it really is awesome. The amount of love and care in these fans is apparent -- they just work and they do it quietly. The included adapter to lower the RPM even more is an awesome perk. That said, these colors are so terrible.

Greater than one weekObviously these are so much better than the stock Nidec fans in this SuperMicro JBOD. Knocked off a couple stars because I had to modify the hot swap cartridge (Its build for 36mm and these are 25mm, there arent thicker ones available that I could find). I also had to grind off one of the keying pins on the 4 pin plug. It was keyed for a 3 pin slot, but the existing plugs will only take a plug with the tabs all the way at the end. From the last picture you can see that the Noctua doesnt have the top pins that let the cartridge cleanly unplug the fan, so if I pull these I have to remember to hold the cable as well.
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.
