> 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.

I buy too much
> 3 dayThese 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.

> 3 dayordered 3 fans to replace the ones in my battery backup.... all i hear is air noise..

> 3 dayFeels well made, delivers on how quiet it is. Could probably cost half as much if the extra 3 cables I dont need and fancy packaging were optional.

> 3 dayPerfectly silent fans -- good airflow.

> 3 dayWork quiet and good amount of air, a bit expensive than another but worth it.

> 3 dayVery quiet fans. Bought two of these to just to provide a little circulation in the bottom chamber of my Cooler Master HAF XB EVO (yeah...probably overkill since most of the heat generating components are in the upper chamber....but figured what the heck since I was populating the other fans with Noctuas). Anyway, when I first powered the system on I had to visually inspect the fans to make sure they were spinning because they were so quiet. How cool is that... (horrible pun)

> 3 dayI replaced both my CPU fan with an 80mm and my case fan with a 92mm version of the Noctua fans. The are very quiet and seem well made. Box included 3 additional cables, screws and rubber mounts in case I needed to use them... Didnt need for my install, but nice touch! Very happy and recommend them!

> 3 dayGreat quality and super quiet!
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.
