I was reading some TEC papers about the optimazation of TEC effiency. Any aways I found a graph that Dt/Dtm vs Qc/Qcm for differnt currents with an optimazation curve. This graphs showed that for our purposes the best operating range is 40 to 60% of current, 50 to 60% of Dtm, and the scary part a maxium of 20-30% of Qcm. So with a 80w cpu it would take 266 to 400 Qcm. I dont know about you but the largest TEC I can get is 275w. This would put an 80w cpu at 50% of Dtm, and 60% of current max. So acual numbers would be 16 amps, 34 Dt and a relatively low power usage of 144w.
