Greater than one weekFit perfectly in an older Dell 790 SFF. Less noisy than the stock fan. Seems to be keeping things cool. Had to use with a Pocaton 5Pin Female to 4Pin Male Socket Connector Jack PWM Cooling Fan Power Cable Compatible with DELL PC in order to connect to the motherboard.

> 3 dayThey may seem pricy. You might not like the color, but these are hands down the best fans money can buy. When they say ultra quiet, they mean it. I put them in an old NAS that was so loud that you could hardly stand to be in the room with it. Now it’s so quiet I forget it’s on, and it even runs cooler than before.

Greater than one weekThere’s a saying “you get what you paid for” and that’s the noctua fans. Noctua fans are the most expensive fans I’ve seen when I was building my $5000 pc. It’s crazy how quiet they can become. The noctua fans are considered ugly because it’s brown, but I actually like the beige and brown color. It’s a nice touch to any classic pc.

> 3 dayAfter reading the reviews I decided to purchase a few Noctua fans for my new PC builds. I was not disappointed. Ive been building PCs for over 20 years and these are by far the nicest fans I have ever installed. They are ugly IMO but if you can get over the color combo you will not regret purchasing these fans. They are packaged better than any other fan and they are dead quiet. Highly recommend!

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.
