> 3 dayI bought a Dell 3880 and its a great little system... EXCEPT THE CPU FAN IS TOO NOISY. If youre in a quiet environment then you will almost certainly notice the noise.

> 3 dayGreat fan, quite. But Jesus, why did they make the thing so dam ugly. Tan and white? Really?

> 3 dayThe packaging screamed quality; adapter cables, extension cable, mounting screws, silicone mounting pegs, detailed instructions on the different uses and possible installation options, wrapped cables, etc... This fan comes with silicone anti-vibration mounts on all 8 corners that are removable, should you wish to. Quiet, this fan is whisper quiet, even at the highest speed. You can connect to 3 or 4 pin terminals on your motherboard. I could not be happier with this purchase & have already ordered a second fan.

> 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.

> 3 daydecreased my gpu and cpu temps by 10c or more while staying quite.

> 3 dayThis review is for both the 92mm and 80mm versions of this model, 4-wire units with speed controlled by the motherboard.

> 3 dayThe fan itself is somewhat quieter than the previous fan (front case fan), but it changes speed erratically, resembling a car motor sound. No apparent change in case temperature. The anti-vibration silicon feet that the fan sits on dont snap into the holes (the instructions dont give any indication), so the fan is kind of suspended mid-case. I hope it doesnt fall off and break itself.
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.
