I've got one of these sitting around and wanted to us it to cool my coffin in my keezer. It's got three wires, red black and yellow. From what I was reading I guess the yellow wire is for a tachometer. I've got a 12V transformer to power the fan, can I just leave the yellow wire not connected to anything since I don't really need to adjust or know the RPMs?
