How to calculate the TEC max temp difference?

[MiracleMan]

I want to know how to calculate it.
It's the latest data I need to see If I will "tec" my Duron or not... ;P

You can't calculate it...its a design spec that's supplied by the MFR...the only other way I can think of to get the # is to determine it empirically...and that is bloody difficult...So get the max. delta T from the place where you bought the TEC
