pielter junction for cooling

[crasch48]

why hasn't someone(you guys maybe?) develop an integrated cooling fin pielter junction cooling rig to enhance cpu/gpu cooling?a double peltier junctionunit would drop ambient temp by 40 degrees.

Because if it could be done, it would have been done.

Companies spend millions and billions on this stuff, because there is money to be made

TEC (thermal electric cooling) is a highly inefficient way of cooling. The reason for this is that it (ultimately) adds overall heat into the system. then the added advantage of any cooling done by the peltier also needs to be able to cool the CPU down enough that the CPU's heat doesn't overheat the peltier, causing it to heat up everything even further and not really do any cooling (there is a thermal limit to how much heat a peltier can handle before it stops functioning properly). Lastly there is the caution of any "lower than ambient" cooling solution. Once you bring your temperatures below ambient temps, you run the risk of condensation... and if you have not taken the necessary countermeasures to combat this, condensation will fry an entire system.

So its not that no one ever does this. Some enthusiasts do TEC for fun and its actually pretty decent when you know what you're doing.... but there are SO many reasons why its not advisable for the general consumer and with how risky it is, I doubt any company would ever offer it as a commercial product.

thanks for the intelligent reply!!

I did this to a 40W quad-core CPU with a 100W peltier plate. It worked well enough but the temperatures were nothing to be impressed about. Trying to cool a 65W CPU resulted in thermal run-away. The way it works it isn't functional for such a task. Now a refrigerator compressor on the other hand would work wonders

Don't let any of that deter you from trying it out if that is what you wanted... That is the territory of the enthusiast after all! we wouldn't be called enthusiasts if all we ever did was the practical things

[crasch48]

that's an idea. or freezer unit? still would have problems with condensation though. what if it helped a water cooling unit?

it would have to be outside like the one on the mineral oil unit. i actually worked on a system in the navy that used mineral oil because of the tremendous heat built up in the transmitter.

[crasch48]

there is a balance in thermal conductivity/condensation where the extra cooling is disapated by the cpu/gpu

i see them coating the mb's with Vaseline to prevent the ice/water from burning out the mb.
