Default Re: Thermoelectric Cooling

Well I won't agree with them being extremely reliable. For a "Good" High Wattage Peltier you'll find that most of them require more than 12 volts to reach there Maximum Potential and they require a lot of amps. Because of this a dedicated 24volt power supply is really needed, something like this.
Mean Well 600W 24V Single Output Switching Auxiliary Power Supply (SE-600-24) -

But now you have the problem of having to turn the 2nd PS on and off. If you happen to forget, as many people have, to turn off the Peltier PS then it (the Peltier) will get hot enough to melt things.

Also, Peltiers basically work by 1 side getting cold and the other side getting hot. The cooler you can keep the Hot side the Colder the Cold side will get. A regular heatsink or a cheap watercooler (like the Corsair H50) will not keep the Peltier's Hot side cool enough to produce any real benefits. So you really need to spend money on a custom water setup. And once you get the Peltier working at it's max. potential you now have to insulate everything good enough to prevent condensation. All of this starts costing money fast.

If you really want to cool things down this is your best option unless you know someone who can build you one.
