Hi folks,

I decided to build a case this summer. I thought to some cooling principles and I retained one that might be effective, but still on air. It is a kind of air conditionned system IN the case.

Here's how it works: (Look at the following sketch)
The air flow will enter the case, will be cooled by going through a Heatsink connected to the cold side of a peltier, and then go into a conduct leading to the CPU heatsink. It will then be ejected in the case, cooling other components as well. Finally it will leave the case by passing though the heatsink connected to the hot side of the peltier, keeping it cool. I thought to put 2x120mm fans as you will see on the sketch but I might add a few others as well.
And I thought to put the peltier alone on a PSU, this is why there is 2 PSUs in the case. Would it be safer ?

Finally, do you think it would be effective ?

Edit: I didnt draw the sides and the top if I want you to see!

seems like a decent idea. i don't see what about that wouldn't work, besides the slight chance of condensation, if your cooling is below room temperature. what wattage pelt do you plan to use?

i'm not 100% sure, but i think a pelt works best when there is a heat source on the hot side. so your setup just may not be as efficient as it would if a pelt was rigged up the way it's supposed to be (on top of a processor).

what about the hot air leaving, right beside the cool air which is entering the case? This is generally why exhaust's fans are at the back and intakes at the front. And with a 600W OCZ psu, you'd probably be ok running it on the one psu, depending on the power of the final peltier of course.

You made me realize that condensation can happen on the cold HS at the entrance. But I don't think it can happen elsewhere, do you ?
Because the coldest in the case will be the air.

BTW, never try to put the heat source( A.K.A. your CPU) on the hot side of the peltier. I don't think it was what you wanted to mean...


Lol I didn't think to the hot air exaust right beside the cold air entrance... But the problem is that it needs to go through the HS and I don't see a way to separate the HS. They should both be attached to the peltier... Anyway I'll think to it...thanks

For my PSU, yes I would probably be ok, but I'm afraid a bit...I don't know how to plug the peltier in it ! And I don't know yet which wattage I should take. What do you suggest, considering it is only for air cooling ?

Edit: I had another idea. I could put a small water tray under the intake HS to collect water from condensation.

You can run into condensation anywhere the incoming air touches if the incoming air gets dropped below ambient by whatever cooling system you set up.

So you mean condensation can happen when the air is in contact with colder pieces ? Then it would happen only on the HS that is connected to the cold side of the pelt ?

And putting a small water tray under it to collect the water from condensation would fix the problem, doesn't it ?

think about condensation on the outside of a cold glass - the cool water/ice inside the glass cool the outside of the glass below room temperature = condensation.

yeah, i definitely didn't mean put the proc on the hot side.

So that's it, the only thing that will be cooled under room temperature(the real) will be the intake HS, as I said, because the air inside of the case will kind of make a new room temperature...
