i didnt read all the posts, but you can use mineral oil and a few other types of non conductive oil to submerge your mobo and cpu in

brut, he's trying to cool his cpu to 0 C, but he needs a liquid that won't freeze at 0c....(cuz water does = not okay)

but another issue = you may find something that withstands 0 C....but I don't know how well it transfers heat...but wait...nm....it's freaking 0c!! lol

but be careful: you may get a frosted cpu....so whatever you use, make sure it's PURE (distilled water doesn't short out electronics, tap-water does...)

your attacking this problem the wrong way.  you want an overly complex solution to a simple problem.

look into using peltiers to cool the cpu, and using water cooling to carry the heat away from the cpu/peltiers.

Then you can either cool the water with peltiers or a radiator.

but by that time why don't you just do vapor change refrigeration?

I've read about people submerging components in super-cooled glisterene (sp). You won't be dunking them, but it implies that it can withstand below 0C temperatures. May want to look into it, just my two cents.

Bazooka audio uses some different kinda stuff for ther attemp to liquid cool their stuff. their site is being worked on now but http://216.133.253.154/ will get you there.

I am trying to avoid having to use peltiers in this little rig I am trying to cook up WS.

  I want to try and make something that is basically a self contained cooling system that only uses power for the pump to circulate the coolant between the tank and the cooling blocks.

  Tereby eleiminating the need for any type of outward appearing cooling apparatus. I.E. a stealth chiller.

  I think the idea will work if a few things are overcome.

1. Finding a non-freezing heat transfer liquid.

2. Finding a fairly inexpensive coolant tfor the tank like freon or similar that is fairly readily availible.

3. Overcoming the condensation problem. Insulation of the tubes and CPU/socket will be a start but I am still tinkering with ideas.

4. Making the unit fit inside a case.   It will be an external unit at first for testing but I would eventually like to make it fully internal if possible.  

I think the mineral oil that brutal suggested will work as a coolant to put in the flowing part but I don't kow what it's freezng point is.  

   Basically I am shooting for a subzero cooling rig that is fairly easy to make from hardware/plumbing supplies. In other words, A cheap ass CPU freezer.

for the second - I know that at the auto-store they have replacment coolants for your a/c (cuz freon or something is toxic) and so that might work for the coolant.... :)

erm, don't most oils start to gel when they get cold?  I don't know about mineral oil, but I think it would.

Most automotive coolants you have to have a lisence to purchase because of EPA regulations now days.  

  Just like in a car you can get oil that flows freely at lower temperatures.

  How else would cars be able to run in the great white north during winter.
