Here is a link to their software page. The program is free and includes a little "thermo electric handbook." Don't worry about the info requested as long as you fill anything in (be correct if you wish or simply put a letter in each box) it will let you download. My main complaint with their program is that it uses only their model #s, but after playing with it for a while you get a real good idea of what TECs can and can't do. When using the Thermoelectric Cooling Selection tab set up your processor amps , ambient etc and it'll tell you what TEC(s) to use and the cop etc...BUT make sure from that page you go to the analysis worksheet and play with the "Set Thermal Operating Point" options. Here you can set hot and cold side c/ws. See what you find on the cold side and how efficiency responds.
Edit: some info c/p'd from their manual, some from memory ....did a lot of reading about this stuff a few months back, played around with a couple of experiments., and reached some conclusions. See what you find
