> 24 hourRelatively quiet and moves a decent about of air. Workmanship is top notch. Just love the Noctua fans.

> 24 hourMy amp sounded like a Vacumm..now is super silent. Best mod ever to calm your noisy devices. I use them in my HTPC build as well.

> 24 hourThe anti vibration mounts included are too short, much shorter than all of the other mounts Ive received with other noctua fans (a lot). I cant reach under the fan and pull the end to mount it properly in my cramped case. The fans feel quality. I just dont understand why the mounts are not normally sized - now Ill probably have to buy new mounts and wait longer to finish my build. unless I can come up with a way to reach under the fan

> 24 hourGood Fan

> 24 hourwould not run at POST and boot up until computer called for high fan speed. BIOS fan test failed. Fan test expected speed of 2600RPM; actual results of 4 test reported 1000RPM each test.

> 24 hourFeels 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.

> 24 hourI 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.

> 24 hourThis is a really nice fan, super quiet. The price for this fan is a little bit more than most but a really good value for such quality.

> 24 hourTheyre very much adaptable to different cases. Super quiet. The evidence I needed that you get what you pay for, and Noctua means truly high quality
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.
