As to the comments re: adding more heat, that may be true, but if the Rad. After the hotside of the pelt and before the cpu etc is able to fully, or near fully dissipate that heat, I don't think that would be a concern. Obviously this would need to be a very good rad - but in theory - it is possible, unless I'm missing something. But I don't think my thermodynamics are that bad. Simple deltaQ + and deltaQ - no?
Edit: Also noticed you're from BC MadHacker, nice to see the representation
