dude, i'm telling you, denatured is a serious solvent. not only that, but have you ever considered flash point?!?!? i'd like to challenge your thought that denatured alcohol can transfer heat faster than water. water has greater propensity to absorb heat energy than almost anything on earth. i am going to check the molecular structure of denatured alcohol (if i can find a model) and rap with you further on this topic.

also, as i previously said, how much damned c02 do you plan on carrying around to 'freeze' an IC?!?!?
