    Peltier coolers

    is it possable to use peltier coolers on a computercase to lower the temperature inside a case? link here if you dont know what one is i was thinking that it is possable and becuase they are solid state they would be more reliable. but most of all would it be efficent for cooling.

    yes it is definitely possible, you shoud visit Swiftech's website (google swiftech) they have a bunch of peltier coolers. Reasonable prices aswell. It's sort of between watercooling and phase cooling.

    they are efficient for transfering heat although you will need cooling on the other side such as water cooling or something, i think, also they may be a problem with condensation

    aye u need to use silicone sealing to effectively seal the peltier in, so it kinda ruins ur board

    Did you want it on the case, or inside the case on the CPU.
    Sounds like the former, in which case, you could well have problems with condensation.
    You can silicone seal with a CPU, but not exactly sure what bit you'd be sealing on your case.
    It wouldn't be very effective, as it'd cool a very small area, and there wouldn't be any way to shift the cold air generated (most would just be exhausted out of the case again if airflow isn't setup exactly right).

    Having said that, some company designed a "PC air-conditioner" a year or so ago, which, if memory serves, fitted in a 5.25" bay, which basically lowered the ambient temperature air at the case intake. IIRC, it wasn't very successful though...

    Peltiers are not efficient at all. Due to this they only really work for spot-cooling, such as a CPU die. For cooling large volumes of air as found in a PC case you're going to want a phase-change system.

    Im not sure if this is the same thing (but it sounds like it is) there is a cpu water cooler which uses a peltier in the water to chill it down and therefore no condensation problem.
    I have no idea what its called all i saw was a picture a couple of sentances in Micromart a few weeks back.
    Rather than cooling down the case.

    Hmm I dont think it was swiftech but I guess its such an obvious thing to do there must be some companies out there that make that sort of thing.

    It'll depend on the heat output of your CPU, but I would have thought condensation could still be possible in some cases?
    If you're lowering the water temperature below ambient temp, then you'll get condensation...?
    Maybe not as quickly, but eventually I would have thought?

    Depends on the relative humidity, but in general anything below ambient will condense at some point so you need to be prepared for it.

    Peltiers aren't good water chillers though. They run hot, and they suck a lot of electricity.
