View Full Version : Peltier Devices and a Zappy Death

I've seen these nifty solutions for CPU cooling called "Peltier Devices."

Theoretically, they can reach 0 deg Celcius, and I'm sure they do, which is why I WANT ONE.

I'm wondering if these things pose the same threat to system stability as evaporator systems? If so, would I need a special apparatus to heat the mobo to prevent condensation from occurring?

I've read descriptions of the items on many sites that manufacture them, yet I've yet to see one warning regarding formation of water droplets on equipment. I'm very worried about getting water near/on my computer, which is why I'm taking every damn precaution to make sure I don't mess up my choice of cooling solutions.

I know a guy that used one, he just sealed it on with silicon glue. He was getting ice crystals.

Mind you, unless you do some serious OCing, they are so not worth it. Like hiring a limousine to go to mcdonalds drive-thru and back.

A good place to go would be Overclockers.com (http://www.overclockers.com). They have links with lots of information on overclocking and different techniques you can use. Here's a link (http://www.overclockers.com/topiclist/index21.asp#PELTIERS) all about Peltiers.

You could also just get a slightly louder/more powerful fan in the place of an expensive cooling solution...

Or you could look into one of the magnetic fans. They can move quite a bit of air and are pretty quite since they are bearingless.

How can it rotate without a bearing? Do you mean motor?

Here is a link that explains the tech behind the magnetic CPU fans.

Edit:
Here is an assembly drawing of one of the fans:

While they still have a single ball bearing in the middle, you'll notice that do not have a ball or sleeve bearings in the middle along with the motor. By using the magnets around the outside they can provide better cooling and radiate less noise.

My computer right now is a noise factory. I can't sleep with it on.

I have 2 front grille fans, 1 cpu fan, a system blower and 3 fans coming out of my PSU.

It's unbearable! I was trying to watch 28 Days Later with my girl, but my goddamn computer was too loud! I had to turn it way up to hear the dialogue, but when the scary parts came along, I peed all over myself, the walls, the ceiling, and her!

Boy was she aroused(?)

Anyway, the main reason I was looking at peltiers was because they're less expensive and easier to set up than evaporator devices. I'll just buy that bulky EXOS thing. The one that sits atop your 'puter!

Garcias un tiempo más.

I believe I'll look into that bearingless fan. Thanks flocito! :wash:

Well if you look into replacing some of your stock fans with magnetic fans you can make your PC considerably quieter.
