Any one remembers the Peltier cooling system ???
AFAIK it was based on freon (like an air conditioning machine, with some compressor behind) allowing you to keep the temp even at 0 Celsius if you wanted. No noise at all (because it doesnt have any fans) but it ate up a lot of power ....

If any one knows where those things have gone, enlight me please

Cheers,

Holy $hit!!!
I once worked as a net admin in one of the biggest Biology institutes in my country and there the guys were working a lot with liquid nitrogen. There i had the first thought of using it to cool CPUs ... but i thought i was too crazy to do it. hehe

If only it wouldn't vaporize so fast ...

I was thinking of buying a little compressor, plug it outside (not in the PSU) and use hoses to reach the CPU ... something like every refrigerator has ... The problem would be, if i use a compressor like the refrigerator does, my CPU will fry in 1 minute. The compressor from a refrigerator only activate itself once every 5 minutes (or an interval close to that) ...

Have any1 tried somethign like this ?

A peltier actually simply increases the total amount of heat that has to be gotten rid of (in order to make one side cold, energy has to be input, which makes the hot side hotter than just the amount of heat coming from the core). However you have a much higher area of contact for a heatsink (or more often a water cooler was used), and the cold side is considerably colder than a heatsink can be, so effectively you can get better cooling. You could use a very large heatsink and quiet fan to get rid of the heat.

However it requires excessive modifications, since you usually have to partition the peltier off from everything else to prevent condensation from dripping water on things. Current aircooling works quite well, apparently better than even peltier and water cooling used to work with older processors, despite increased amounts of heat and smaller contact areas on the cores. Peltiers just aren't really needed even for heavy overclockers. It would be interesting however to see results anyone might have on current use of a peltier and how it relates to ability to overclock. I would guess that with the now multiplier locked lines from all manufacturers, the bus speed limitations will prevent a peltier from significantly increasing overclocking ability, whereas with older lines, you could use the power of a peltier to allow the clock speed to go very high independently of the bus speed.

What happened to peltiers is that you forgot about them and haven't paid attention to them. They are still being used freely in the watercooling world

I think you are talking about phase-change cooling though, and that requires a compressor of some sort. Either way, this thread could have been prevent with a search.

Oh i'm so sorry i forget things or ask questions ... and also can you teach me how to do a search at www.google.com ?
Thank god there are nice people like you giving such useful information.

But still ... threads in forums are for asking questions and get feedback from people in a short time and up to date.
Still ... for making you understand my stupidity or whatever you wanna call it, i asked that question seeing that in this forum nobody talks about peltiers anymore ...

Nobody talks about peltiers in here because everyone is preoccupied with "where to buy neoprene" or "brand new 430W Antec PS compatibility?" or "how do I make my computer quiet" or "how can I make my computer like a Dell?" or "which is the best heatsink?".

If you want to see more discussion about peltiers and other hardcore stuff, register and post at www.hardforum.com I post here seldomly, simply because there are no strict moderators There are also a few of my buddies here, but they also post over at the Hard Forums.
