Greater than one weekI bought two of these to replace the cheap fans in my rackmount case. Not only are these Noctua fans well engineered and designed they are dead quiet. I used the rubber mounting grommets that are shipped as an install option in lieu of the metal screws. This really helps reduce any vibration noise on the case. Noctua products are simply hard to beat.

> 3 dayI do a lot of custom builds whether it’s small electronics, emulator boxes, 3-D, print builds, etc. this is the only brand fan company I will use. Rocksolid great cooling you don’t even hear them on.

> 3 dayLoved their care they put into packaging and attention to detail. Ordered 2x 80mm fan for my mini itx and it works wonderfully. silent and keeps my case cool as exhaust fans.

> 3 dayyou can tell its nice cause the box it comes in is heavier than the fan itself

Greater than one weekBest fan manufacturer Ive found. Ive experienced fan failures and excessively noisy fans over the years, but never from a Noctua. I use them in all my computer cases anywhere a fan will fit, and my first Noctua CPU fan/heat sink combo (NH-C14 on a 1st generation I7 processor) is phenomenal. A perfect compliment for an SSD, you may have to look twice to see if the PC is on!

> 3 dayUsed these fans to replace the factory fans in my Inuke 6000dsp amp. These fans are so much more quieter.

> 3 dayI replaced some older Lian Li case fans with a few of these Noctuas and I could not be happier!

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.
