Greater than one weekI used this fan to blow air over a 4-HDD RAID in my desktop. It also helps draw in extra fresh air for my CPU. I mounted it to a custom 3D printed frame in the 5.25 bays of my computer case. It works well and definitely moves some air without being too loud.

> 3 dayVery pretty package. Very quiet. Expensive, but nice mounting options. Doesnt blow much air, but what do you expect from a 1400 rpm fan. I took a point off because of its cost.

> 3 dayPurchased this fan to replace a noisy stock fan. I was very impressed by the results. The fan is completely inaudible over other case noises, and judging by my temperatures, is still moving a substantial amount of air over the components. Highly recommend for anyone who is looking for a Quiet fan with a capital Q.

> 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 weekEssential component to a recent ITX build of mine (Fractal Ridge). You get what you pay for with Noctua - in this case, that means okay/good CFM at lower speeds while also yielding extremely quiet noise levels.

Greater than one weekI 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 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.
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.
