For the exact figure you would need to find a chart. From studying charts generally it is possible to deduce that the hotside load is roughly 225-250% of the Q at the operating point, not Qmax.
You wont be far wrong using this for a good ballpark figure. So long as your Q is close the maximum coldside load. You can reduce the figure a bit the higher your Dt.
So if at the operating point (V) your TEC has a Q of 200w you can expect the maximum off the hotside to be in the region of 450-500w. Of course remember this is a ballpark figure for the maximum not what will happen all the time. As the running variables of the TEC change, particularly the coldside load if we are talking about a direct die cooled CPU, so too will everything else including the hotside load.
If your were to power one
300w Qmax TEC at 24v (its a 31.5v part.) you could expect upto
600w off the hotside BUT if your actual maximum load on the coldside is less than 240w (Q) the maximum heat off the hotside will be reduced.
So you see there are tons of variables in this.....
....wait and see. Over to you Elloquin.

Just the TEC hotsides I hope.....Opps sorry you said radiator wise.
