Thermo-Electric Cooling

[Dobby102]

Has anyone had any experience using thermo-electric coolers. They seem to be a cheap way to have a rig running bellow zero but no one seems to talk about them.

 

Is there any serious flaws to using them and what considerations do I need to take into account? Should I have one between the CPU and a heat sync or use it to cool fluid to be pumped around the system?

Because they aren't that effective.

You would need a lot of theromeletic units to get it below zero. I tried this once with a core 2 duo and at idle it was a bit under ambient, and at load it was a few degrees cooler.

 

It also uses lots of power(a few hundred watts to get it under zero).

Worth it. (I don't pay for my electricity per watt and have an op PSU)

It's not really suitable for most situations since you need double or more the cooling wattage of the peliter of the CPU's to get proper cooling especially if you try to get it sub ambient not to mention the issues with moisture.
