Alright,

I have not attempted to overclock or build a PC since the Pentium 100 to the first model Athlon. I do remember attempting to use a peltier just for fun. Anyway, it seems the common problem to using a peltier is condensation. I have a concept in mind which would allow the use of a peltier, without condensation, but I do not have the technical knowlege to explore the possibliity. I'm hoping that ya'll, being the experts, could confirm the validity of my concept.

1) Use some kind of mid to high range air cooler with PWM.
2) Between the processor and the heat sink of the cooler, use a Peltier.
The first two steps are standard. The next part is what I need your technical knowledge for.
3) Use some kind of thermal, automatic control to maintain a steady tempature of the cold side of the Peltier, similar to the way the PMW speeds up or slows down the fan as needed.
4) Set the thermal control to maintain a steady processor tempature of between 40 and 50 degrees celcius, or any tempature considered low to normal; and more importantly, far above condensation.

The idea is to put a working system into a daily use computer, allowing light to moderate overclocking, while skipping any problems with condensation.

The possible benifits are, as I see them:

1) A very steady tempature on the processor, no matter the usage.
2) With an appropriately powerful peltier, the ability to overclock the processor without a major change in tempature, just power usage.
3) No Condensation.

Please let me know if something like this is possible, and if it is, how to do it.

Thanks!




After digging a little further, I've come up with the questions that need to be answered to allow the use of an automatically adjusting Peltier without the condensation issue.

1) What type of power regulation should be used?
2) What type of tempature sensitive automatic controller for the power regulator should be used?
3) where can one purchase the answers to both question one and two?

This subject of the following link seems to indicate that a standard PWM (one that could handle the wattage) would drastically shorten the life of a Peltier, which would put a limiting factor on the type of power regulator to use.

These links have some general information that seems to apply to this subject.

Solution
Pelts can't keep a modern CPU cool anymore. They aren't big enough or able to handle the wattage. And you have to watercool the hot side if you even try it these days.
