submersive cooling project using water

Avatar28 · 04-17-2002, 07:11 PM

I was thinking about attemping a submersive cooling project with a twist. Instead of using Oil or Flourinert, I want to use water, albeit highly purified (Deionized) water. The water has a minimum resistance of 18 megaohm, so hopefully should be fairly insulating.

I'll have to purify the boards and container first to minimize adding ions to the water. Anyone have any thoughts, ideas, or suggestions on this?

If I can pull it off, I'll make sure to take some pictures and put up a website about it.

Quite the risky one, but if you do, I would suggest getting a spray on plastic (adhesive?) and just cover the boards in the stuff, then all you would have to worry about is the connections between the cards and the mobo (well, any of the connections).

I always wanted to submerge a 486 in water by covering the entire (and I mean entire) thing in hot glue

why cant you use Plumber's goop to seal a processor socket instead of using silicone?

plumbers goop has acetic acid in it and will damage the PCB over time.

Water doesn't stay deionized. If you get it to work at all, then after a few weeks CO2 will diffuse in and then convert to HCO3- and wreak havoc. Thats assuming you can get all the ions off your components to start with (doublful). This is a pretty poor idea (take pics of the aftermath, but don't get electrocuted).

Someone at overclockers.com had the suggestion of putting the deionizing filters from a small home water deionizer filter into the water. That way they should take up any free ions in the water.

I could also try covering most of the components with some sort of conformal coating except for where it NEEDS contact with the water.

Proceed if you must but you will get no benefit as you will still have to route hoses so that water gets to the bits that need to be cooled. You will also still need to put heatsinks on those components (the proc. at least) don't have enough surface area. If you do proceed accept my condolences for the loss of your computer.

wierdo. You sound like a curse. "Proceed if you must. Pick one door. You will die either way"

Very possibly not. But I still have to try though. :-)

Try with a mac first... those deserve to die

Too bad I don't have any extra Macintrashes lying around.

Talk to your school's network admin or some local school network admin. See if they could donate u an old 486. Or u can call a local PC store and run it on it. I am not sure if it is possible to overclock a 486 but u can use it to see if it can work for hours under full load with that stuff on it

yeah, please dont kill any good system... ive got a 486 ill trade you for whatever you're going to do it on. I need a better web server...

I have ever intention of starting on an old 486. I've every intention of testing it with that and making sure it's completely safe before I put any kind of decent system into it. Worst case, I've got a couple of ideas even if the pure water still shorts it out.
