Again havent used one but done a lot of research and concluded, they are for major tinkerers with money to spare.
JoeF's comments are true and I get the feeling they are not appropriate for Athlon Processors as they run hotter than P's.
Peltiers are only 50% thermally efficient. That is - they generate about as much heat as they transfer from the cold face...that is if you want to move 60W's from your CPU (about average) then your 75W Peltier will emit about 120W. In Joefs case and I think in the case of many of the newer "hotter" CPU's (athlons in particular) this results in an overloading of the HS/Fan...ie: the HS/Fan cant remove/balance all the heat fluxes at a normal 40oC until it gets up higher - say 50 or 60oC, where the HS/fan works more efficiently (things loose heat quicker the hotter they get)....
So its all a heat balance (that's okay - I'm a process engineer). The most assured way - as Joe suggested - would be to sandwich the peltier between the CPU and water cooler/HS/Fan combo. I think this is needed to remove all the extra heat that the system generates....
Any contrary or abusive comments appreciated on these ramblings....
other considerations - they cost some money to run..I calc'd about $70 per year in power consumption
