I recently installed a new Rambo v1.2 board. I was able to upload the firmware and recalibrate the extruder just fine. However, there is one question/issue that I may have.
There are no pins for the fan blowing on the electronic board itself. In the upper right corner where it was on the original board, there are just holes for pins.
First, should they be there and it was just mis-manufactured or is this by design?
Secondly, how important is it to have a fan actually blowing on the board itself?
