New AR4 MK3 Robot fan cover for Noctua fan

The original fan cover has been designed for plain fan. Problem, such fan is extremely noisy.

One of the AR4 community suggested to use the 40mm Noctua fan.

To take full advantage of the Noctua fan I decided to use a better suited guard. The new enclosure also provides a better air flow.

It is possible to use the fan with or without the “Low Noise Adaptor”.

Better without it for the main enclosure to provide more air flow.

Refer to the photos available on Printables to have some examples on how to install ir. Feel free to ask if needed.
