Re: Is liquid cooling really "greener"?
In simpler terms, you need to cool the air much more and move more of it to get the heat transferred from the chips. You then need to compress the air to heat it up to get the heat out of the air into the environment, you then need to cool the air to start again.
Water can pretty much flow in at room temperature, get heated to chip temperature, flow out, get cooled back to outside air temperature and repeat.
