Thermal enterprises CP1 12730?

http://cgi.ebay.com/Gigantic-62mm-54...QQcmdZViewItem
It's a 545 watt peltier cooler that claims it can operate 0-16 volts and 0-32 amps. Has anyone actually tried this because I am very low on time and need to know how far I can push it without it blowing out. Also I'd like to know what kind of differential I can get from one. Currently I am using two peltier plates (side by side) with 12 volts and 18 amps in a series circuit with a heat sink running under it and I can get the temperature down to about 28 farenheit. If I were to add two more plates, one under each of the two existing ones, and add 12 more volts and 18 more amps in series (or in parellel if it's recomended), should I expect a major drop in the temperature? I need it very cold (-15 farenheit). Anybody have any answers or solutions; I am a noob in desperate need.

I don't doubt the existence of a 545 watt peltier. But its going to be a bitch to cool. Good luck and read up.

Well I can't say I know enough to refute your claim but that is what the provider claims (check the link). Also did you mean that the higher the watts of the peltier, the harder it is to cool?

Notice it says "maximum power consumption". Doesn't mean it can cool 545 watts just means it will take 545 watts. Optimal efficiency is probably half that. The better you cool the pelt the better it will perform. For below ambient you will probably have to water cool it.

I'd think that water is the only option in this case... wouldn't the output be near 700 watts or more?

I'd imagine its cooling capacity is similar to the Winstch Labs 437 watt one. 545 watts is the electricity consumed; it's cooling power will definitely be less than that.
