as long as its below -70c I could use it with my chiller in the fashion you are suggesting...

there in lies the problem it has a fairly low freezing temp (let me find the temp I have it here some where) but it gets very viscous the lower you go you would need a very strong pump to run it

edit no it wont dig that low. freezing temp is around -30c sorry m8

edit 2 now there was some stuff I was looking at that 3m caries that is non conductive that got down past -100c (I think) but the stuff was not cheep

You wouldnt need to pump it at all if you had CPU + 2x GPU's at -60c running...the tubing going through the oil would chill it instantly.

ahh I see what you are thinking now

I was thinking of my rig

btw I think you might like this mini mod I made for one of the cards to push more oil through

yes I glued a cpu fan to the card

In that article you reference, they don't even use water. They use oil that is inside the case. The case is the reservoir. They use tubing to direct the oil post radiator to the block, to cool it down then it gets dropped back in with the rest. Your misunderstanding the concept and making invalid recommendations.

Also, where does condensation come from? Not where as in how, but where as in your example? You would have to get temps next to freezing to worry about condensation. The only ones that need to worry about condensation are those using TEC's and LN2.

Yes, in the PC I linked they are using Oil, but using water would be more effective. I was just looking for a pic with water blocks submerged in oil to better describe what I was talking about.

And yes, any time you have a liquid with subambient, or temps lower then the other side, you have the potential for moisture to condensate on the opposing side. It's science.

"Water vapor will only condense onto another surface when the temperature of that surface is cooler than the temperature of the water vapor" wiki quote

The whole reason I suggest water is due to the thermal dynamics of water compared to oil. It has been proven many times that heat can be transfer thru water much quicker then thru oil.

CL, I like the idea of getting the tubing or piping so cold you don't have to worry about removing any heat from the oil.

I apologize for the questions as I haven't been following this thread closely:
Why did you take the stock fan out of that VGA?
Did you have any problems with thermal paste so far? Is the CPU socket sealed?

Why did you take the stock fan out of that VGA? to see If a higher cfm fan would help move more oil and it dose

also just to try it out

Did you have any problems with thermal paste so far?no

Is the CPU socket sealed? no

hope that helps clear things up

How, in this situation is there going to be condensation that he would need to even worry about this situation. Is he running a TEC, or LN2, or even running the radiator in the snow, or in ice water? What about this build does running this setup in oil, help him when talking about condensation?

Thats what Im trying to understand. I understand condensation. I dont appreciate the science lesson. Your beating around the bush with answers. Read my post more clearly next time.

To OP: This looks like its going to be a blast to run. I was just talking about running a 200 gallon oil system. But before I could even start making plans, I lost my job. So that will come when it can. So I look forward to your outcome, and hang in there. It will come together soon enough.

Thanks for the replies. I have to leave really quick; so if you want, try googling around for oil cooled computers. It looks like sealing the CPU with silicon is a very good idea as the properties of the oil combined with hundreds of pins really close to each other don't quite mix very well. Just a heads up.
