Re: water cool video cards
Yea no problem I know it can get confusing. The one thing I do know is from tests done a few years ago by Cather (very well known in the WC community) there was minimal difference between actual temperature results for 3/8in and 1/2in ID tubing, but I don't know how true it is today since we have more powerful pumps and so forth, but you are safe to go with either one. I think most important now is how thick of a tube you can get through the back of your case. Make sure to keep under 3/4in OD with your case unless you want to drill a larger hole and install larger grommets.
