The mainboard fan on the Aquila is loud!
I designed a new cover and am now using an 80mm 24V fan.
I added another stl with thicker walls and a mount point - slide to get it to fit.
These fit Aquila O1 and C2 (maybe others)
As a side note: the mainboard fan should always run so the stepper drivers do not overheat and cause layer slip.
