so what kind of advantage do you see in waterchillers? if you dont have temperature control like that unit, you are going to have to worry about condensation (assuming you are using some pretty powerful TEC). That just add another level of complication to the direct contact method. Second, why would you want to cool the water and the cpu when you can just cool the cpu? anyway, i am not trying to stop you from doing your project so good luck
