If the power supply can deliver 24volts at 9amps, it would be no less happy than if it was providing 12volts at 9amps with a few voltage regulators.� Voltage regulators seem like the least ideal way to go.<br><br>ADDITIONALLY, TEJ's that I've seen are designed, actually, for 18v.� This seems to be the standard.� Just because they were marketed for a 12v power system doesn't mean they can't be used for something more.� Find the source of your TEJ's and read their papers.<br>
<br>If you want to get crazy, so long as they don't get too hot, there is really nothing preventing them from taking more voltage.� An "18v" TEJ can probably take 24v...but I won't take responsibility if you smoke them ;-)<br>
<br>The trick with TEJ's is that you need a TEJ that uses <i><u><b>AT LEAST</b></u></i> as much power, in watts, as the heat you are trying to dissipate, in watts, and then you need a slug of metal that can easily dissipate all that heat.� You REALLY need to over design your cooling system.<br>
<br>So, whatever you are doing, using two TEJ's in series will allow not just for double the cooling power, but also double the surface area for heat sinks.� This fact alone makes me side with the "run two in series" folks.<br>

That would work, but the power supply may get unhappy (depending on<br>
the type, either very hot, or shut itself off) about having so much<br>
current drawn.<br>
