Will this work? (Hypothetical Peltiers)
« on: April 12, 2002, 11:56:00 PM »

I've been thinking about a cheap way to emulate air conditioning in my PC. I was wondering if you built a fan duct that ran directly over/around your processor (Intake--->Duct--->CPU/Heat Sink--->Duct--->Outtake)and placed peltiers inside/on the duct, would the peltiers effectively cool the air inside the duct without all the condensation issues?? Thanks for any help you can give!

hmm....let me see if I got this right:

so you're gonna have an intake to push COLD air onto the HSF...and then an intake to take away the "hot" air???


well personally, you only need the intake....the exhaust fans in your case should take care of the exhausting of teh hot air...


but for the cold pipe... you'd probably have to stick a hsf or something in the pipe that'd let the air get chilled as it enters (this i called an air-chiller and the idea HAS been done before...although I don't know how the persons attached it to their case) and so I'd imagine you'd use a pipe of some sort to direct the now cold air to the cpu. This is good and all, however, I don't know if you'll escape the problems of condensation...

most likely the water won't condense on the cpu hsf....but it'll probably condense in the pipe...and I'd fear that this would then drip outta the pipe in/onto your computer's insides!! :(

also note, that a pelt has a hot side too...so you'd have to devise a way to get the hot side of the pelt on the outside of your computer, or else you might negate the effects of teh cold air by having the warm pelt side in the pc...


wow, that's a lot to think over....whew!

yep, condensation would still be an issue. Its like a glass of cold water on hot day when you're sitting outside.  even thought the glass isn't freezing it still below the ambient temp and condensation forms on the outside of the glass.

And cooling the peltiers almost makes it not worth the trouble to get the cooler air into your case.  If you want a cool pc build it in a mini fridge.

and the only way around the condensation is to run the air through a metal screen so it had a place to condense. you might want to rig it up outside of the case as a test

Thanks everyone. If I end up doing it, I'll post the results!
