ok i did a project for a tech school that i attend and we used peltiers to cool water down and then ran the water to different parts ie pentium 3 650 and a voovoo 3 3000
Distilled water is the best to use, it suposly wont conduct electricty and it has verry few impurityes in it so it will cool better,we tried a couple different mixes, alchol(rubbing kind but 80 proof wont burn) and rv antifreeze mixed 50/50 with water, see we would of had ice if we had better heatsinks on our peltiers, we used super orbs from 3dcool and they worked ok, but we took the square bottoms off and thet left the edges of the pielters exposed so that only the center was cool. bactiera might be a problem for you see we siphond the system the first time by mouth and it created bacteria after a while, we got a pump that you can attach it a drill from sears and used the handymans secret wepon (duct tape) and taped it to the hose, after that we got a bleed vlave made of stainless from a plumbing supply store and fitted it to the system to bleed the air out you will want to get as much air out of your system as possable but go with plain distilled water to make a long story short
