Ice cold? funny. Anyway I have a question that may have already been answered here,but I'm too busy tweaking to search. I'm forced to go liquid cooled giddy: I swapped out my gfx5500 for a new ati x1600pro (the 512mb one) and this thing is WAY too loud. I think if my case had wings (and wireless hook-ups) it would fly....seriously, this thing is ridiculous. So my question is, what kinda liquids (or low pressure gases for that matter) could I put in a water cooling setup that would get colder than water? something safe for pumps, and non-corrosive to radiators. It's ok if I have to build some things, I like tinkering. any input would be great. By the way, I got my 2.8 prescott to hit 4.2 ......on air. It crashed shortly after, but thanks to asus, I'm ok.
