I am converting a mini fridge to a kegerator in the near future. I have seen a couple of ways to keep your beer lines cool as they enter the tower. Some have drilled two small holes and ran copper pipe to the tower, some one large hole with copper pipes, and some with a large hole and an electric fan to cool the tower. Anyone with experience in any of these methods? If you did run a fan, how did you wire/connect it? I am not planning on drilling a hole besides for the tower, as I am keeping my CO2 tank inside the fridge.
Thanks in advance!
