"Hi, \nI want to put a second fan for pla cooling since with just the one that comes I can't get perfect complex overhangs.  \nThe think it's that I don't know the specs of the fans that I should Install since there isn't a github for the umo+ and since it uses the board of the um2 I'm kinda lost on what voltage/serial/parallel? Configuration of fans I must buy.  \nThanks! "
