Peltier Condensation Prevention Guide
 

Conventional methods for the unconventional process of peltier cooling a processor have always included insulation. How about a method with only minimal insulation and none around the actual processor. Well its just been done! How will peltier cooling change now? Read Jason's article to find out how!

Peltier Condensation Prevention Guide

Nice to see someone trying new things!
 

...and here I thought the inventors and innovators all turned to "lazy" overclocking with all the off-the-shelf stuff available now -- Congrats!

Very interesting idea--you should talk to Dennis at DangerDen about this; I'm sure he'd be interested.

Very Nice
 

Good s*** :clap:
Mean idea, im keen to do sumpn simmilar to mine now, itll realy help coz my silverprop block has no overhang on the socket which it makes it hard to insulate. I wanna get on to it now but im gonna have to wait a month or so for some parts (my student budget) so when i get all that sorted ill try it out and maybe throw some pics up of my success (or failure as the case may be).

How did you get the air out?

y not use artic sliver ceramic?
it's non conductive or captive.
or just use the stuff vaporchill use?
some sort of silicon paste.

Heat formed shroud
 

Anyone know of a material you could heat form rather than cut and glue?

Wouold be great if the container was seamless.

Shroud
 

What im gonna do is go looking in shops for a container the right size and use that, itll mean u get a nice seamless finish but it wont be 100% DIY, dunno if ur finiky bout things like that :) + i dont imagine itll set u back any more then you'd spend on a DIY shroud (unless u alread have the parts :P)

Be careful if you use the silicone to bond the container, its not so easy to remove. A flexible rubber or easily removable seal is better.

Heat
 

Hi Jason, i was just wondering what wattage pelt you were using and how hot did the air inside the container get???

Hi,
You might think about installing a one way check valve , and using a
vacume pump with gage. This would help remove air from inside , and also let you know if theres any air leaks. As mentioned by Jason
using a good rubber seal, because some silicones will cause corrsions.
??? what do you think. :wavey:

Sounds like a good idea. Id like to try the vacuum idea with the check valve but pulling a vacuum may warp the motherboard and also it would be beyond the abilities of most home users. My aim was to develop a process that could be easily duplicated at home with the minimal of supplies and effort.

I doubt a vacuum would damage the motherboard, but the high pressure differental will certianly cause any weakness in the seals to give way.

With the dessicant, is there much to worry about?

Another option is to replace the air inside the cube with something without any water in it. Nitrogen and argon are good coices, as they are harmless and since they are heavier than air, you can "pour" them in to insure you get all the air out. Gas supplies can be easily gotten at local welding supply shops.

For some motherboards.. what about puting studs in that can pass through the four mounting holes and then be screwed down to make a good, firm seal against a rubber gasket? No glues needed.

This thing still running?

Jason, I have an idea I'd like to see tried, yet I have no idea when I'd have time to try it. It may be a much less expensive and easier implemented alternative.

Here's what I suggest: Using a old board and chip to make sure it's going to work before trying this on something you can't afford to lose. Why not stick a copper block on the cpu and silicone around it, then hook the peltier to it, then hook on your water block, etc. Paint the underside of the board with liquid electrical tape, then slowly pour melted candle gel over the board until it's level with the center of the first copper block. I don't think you'd want it too close to the hot side of the pelt.

It should seal the board from condensation permanently. If you wanted to spruce it up with LED's, EL-wire, or something, just use a screwdriver or other stick-like thing to push it into the gel while it's cooling.

I'd make a mold around the cpu to set the gel just there. Only drawback I can see is that you'd want the board to stay horizontal.

What do you think, is it worth a try?

I agree that would probably work but the idea was to come up with something less drastic. Most users wouoldnt go as far as melting wax or painting their motherboard. BTW is there any electro static problems with spray paint cans? Your idea is sound, and many more radical enthusiasts have done very similar stuff, including me. But most typical users interested in sub ambient cooling wouldnt go that far.

I've read on a couple of sites where spray paint cans of water repellent were used with success.
