Hi,
Another version of the fan replacement from Noctua (The NF-A4x20) for the main X1C board cooling fan.

In the photos you can see the old vs the new, the old bad profile etc..

By the way my profile designed to be printed with the 0.6n for stiffer and much durable print against heat.
It will fit only the A4x20 version and not the A4x10.

A simple design that helps the printer be much quiter even after the last update and much cooler!

PEACE!
