ice cooling

how this possible? wouldnt it short .... & ice has to melt some time...

what causes a short is the minerals inside water, exactly why you use distilled water(no minerals). don't know exactly why it wouldn't short but it's just water condensating because it's so cold. it's so cold that the air around the source of cold is freezing.

and if it melts then is allowed to evaporate all is good.

Its the water in the air that are condencing. So its not distilled.

well i was kind of applying that towards watercooling too.

But what is distilled water?

Simply H20 which has been chaged from liquid to a gas and then changed back to a liquid, thereby leaving the impurities behind.

The second stage of this process is essentially what happens when atomosheric water vapor forms as a solid on the frozen components (deposition) and then melts again.

Granted, there may be some trace elements from the atmosphere (more in some areas than others) but the water should be fairly pure.

Just a techincal point; not to detract from the fact that any water, distilled or not, is not good to have sitting on your components

So what was the verdict on the picture in the OP? Surely, eventually the ice would melt?

Was this on a phase cooling system? Then it seems that at some point, you'd have to disconnect it (like when upgrading or something), and the ice would melt and ruin your processor... I'm waiting to get proved wrong though...

You can submerge your processor in water... or just about any solid state componant, and not damage it, as long as there is no power running through it.

Normally, when you supercool your processor or video card, you coat your board with something (teflon? not sure what it is) so the frozen water is not actually directly on the componants. Perhaps you just can't see it in that picture.

the board is coated with dielectric grease to prevent the water from contacting it. its pretty much a grease that doesnt conduct electricity. between that and insulation which that setup is obviously lacking... there shouldnt be a problem. that looks like it might be a beauty shot, where its run without power just so it'll condense and get everything around cold and look pretty with it all frosty.

Thats condensation from the air while using sub zero cooling such as a pelt, phase change system, or DI/LN2. as long as it doesn't start melting until you shut off the computer your pretty much good, otherwise i'm sorry to see your nice hardware fried.

four4875 · 10-24-05, 10:37 AM

umm... why couldnt the frosted condensation still conduct? its still the water with the minerals and the such...

aznkc730 · 10-24-05, 10:18 PM

if its coated with dielectric grease, there would be nothing to conduct electricity to. In the end, the image is definitely possible as long as either : A) the board is properly insulated from it (spray on teflon coating/ dialectric grease) and kept at that temperature by the peltier or whatever, or B) the power is off, no electricity is running through it
