Before I discovered Kryotherm, I setup a spreadsheet to calculate performance of any TEC based on the commonly used specs:

Qmax
dTmax
Vmax
Imax

It's very crude in comparison to Kryotherm and comparing my spreadsheet's results to Kryotherm's for a 172 W TEC generated errors as high as 5C iirc. (Although that error was at an operating point far away from typical.) It seems to give fairly accurate results under the operating conditions typically used in CPU cooling.

If you are interested in playing with it, let me know. (I had attached it to a post at O/C'ers, but they have gotten rid of attachments since.)
