endothermic reaction

Anyway we can incorporate this into our heating problems? I mean there has to be something other then water/air/phase cooling..... then again phase does this but damn expensive.

... you sound like someone from the big bang theory

Not really, regardless of what method you use, you have to put the heat somewhere.

In the case of my benching using dry ice, every bit of heat i soak up with that dry ice has already been dragged out of the dry ice when it was manufactured.

Phase change is the best example of this, it takes a bunch of heat out of the cpu and puts it in the condenser.
I'm not aware of any endothermic chemical reactions that reverse easily enough to use for pc cooling.

I'd also be high maintenance...and that's no fun.
