The cooling fan in my control box has gone out. The specs on the fan is 120mm 48V .06A. I have a brand new fan on hand that matches those specs except it pulls 0.12A. is this within the acceptable current range for the avid driver board?
It’s probably fine… It’s sharing power from the those big power supplies that run your motors and there should be plenty of power to spare. I wouldn’t worry about doing that. Just get the polarity right 
To be clear, the fan was blowing OUT of the enclosure and creating a negative pressure space?
