Is this usable?

post #1 of 9
Thread Starter 
Recently managed to snag one of these. "4 A peltier cell with 12 V feed,
cooling max. 20°C below ambient temperature, heating max. 65°C".

Was thinking about maybe using it to blow cool air into my gpus (going to pick up an msi pe 670 for sli in about 20 minutes), or just all around lower temps in the case (will be building a custom desk drawer for component housing in the near future). I doubt this thing would be able to lower temps enough to worry about condensation, but if just bolted a big ass heatsink to it and used it as an intake it should act as a condenser right? I'm not overly interested in the water applications though, i understand it would be much more efficient but I would have to buy all the gear.

If not i can always just keep it intact and use it for it's intended purpose haha.

You should just use it as is lol

I wouldn't try and use it to chill the air. Things like that are not built for a continuous heatload, so subjecting to to sustained use such as it would in the case of an air chiller may cause it to simply burn out :/

Thanks for the advice. I decided to disassemble the cooler anyways, i was told it didn't work and i should throw it out (hence why it was free). Turns out the TIM on the hotside was nonexistent. And bonus, I managed to get it apart without breaking anything.







This is the stats for the peltier

Yeah, see that has a Qmax of 50watts XD that's pretty scrawny. Do you have a liquid cooling loop by any chance? If you do, and your radiators are intaking air, you could use that peltier and build a baydrive air cooler, with the hotside venting it's heat via a heatsink/fan out the bay. This would have a MINOR effect on internal case temps, but if anything in the case is still aircooled, such as your graphics cards, it might give you a bit lower temps, and since the baydrive contains the peltier any condensation would form at the baydrive air cooler, so you could just build a little tray/res to gather it, so there would be no risk of hurting your comps internals via condensation.

It would probably have very minimal benefits, but it would certainly be a good conversation piece.

I don't have any liquid cooling, so getting into that would be costly. Doing some reading up on all this, it's basically building a dehumidifier doing it as an air to air. The heatsinks and circuitry could also be used for other things, but mostly i'm just going to play around with it. I also found these on amazon for about 6 bucks each, so even if I can't work out how to apply it in an air to air situation I could find other applications for them.

Yeah, getting into liquid cooling would be expensive, unless of course you just get these

They have shoddy performance for CPU cooling, but standalone TECs have a much smaller heatload than CPUs.; biggrin.gif

Forr about 30$ (after rebate) you could get one for the hotside, and one for the coldside, or just air cool the hotside. Keep in mind, if you use it on the coldside you'd probably need to drain it, then refill it with a subzero capable liquid, to prevent "frosting" on the CPU block. So add another 20$ for that coldside.

Again, still only like 50$

For 20 bucks I think I'll pick one of those up anyways, i'm not sure how effective it would be on a coldside, but the idea of cheaply being able to route heat away from the hotside is enticing.

I have a buddy who works for a company selling steel and aluminum (he says the thinnest sheet aluminum they sell is 0.0299", or about 0.75mm) , so I may toy with the idea of building own sinks.
