SUBMERGED BUT NOT COOLED SYSTEM

captain · 04-24-2001, 06:32 AM

Hi there again.
I'am going to post one more nutcracker for you. First I want to appologise if somebody thinks this is a stupid idea. I'am just doing some cyber philosophy.

lets start.

I'am new to peltier cooling but I have learned one thing and that is that condensation is a big problem when trying to achiev zub 0 temperatures.

So why not submerge the motherboard in a liquid that is not electrically conductive.
this should be easy to find since you are not going to freeze the liquid. Just use it to remove the air so condensation will not harm your system.

Assume we put the motherboard in case filled with Artic Silver. Should this not prevent condisation and also remove the heat from the motherboard. Then we will not worry about condensation when we put 172watt peltier (with watercooling) and 120watt for the GPU. uuuhh I'am right

hahahaha.. They say "minimally conductive".. That doesn't mean non-conductive. You'll zap the hell out of your board. But I do see your idea.. Maybe you should use something like mineral oil instead.. Just seems extremely messy to me.

actually you might have something there.

A problem I encountered is that my motherboard gets cold, its got 3 layers of copper in it after all.

If you made a waterproof box around the waterblock and general cpu area, and ran warm/ambient temp liquid through it, you shouldn't have condensation due to cold components.

That is a pretty cool idea, but I'm not into that whole submerging thing. But your idea got me thinking... what about a projejct box that surrounds the CPU / heatsink and is air-tight? There are two hose leads coming out of it. The two leads are for the mineral oil to circulate through a chiller... What about that? Could that work?

yeah. won't you still end up with an extremely cold motherboard though?
It DOES have 3 layers of copper running through it that will conduct the heat(cold).

also the box would have to be very well insulated.

but aside from those problems, it does sound more efficient than a copper waterblock.

This has already been done with a liquid called FLUORINERT. check it out at www.octools.com
