Chilled Water and Mineral Oil Computer Project - Page 2

post #11 of 17

I think that this would be risky because any liquid that is outside (such as the tubing inside the case, or the waterblocks) would have a risk of condensation because their surfaces will be colder than the air.  The colder they are, the greater the risk of condensation.

 

What you can try to do is see just how much condensation you might get by having a glass of ice water sit out for a while in the room where this system will be.  Or, just take anything that's cold out of the fridge.  You'll need to be able to easily spot any condensation.  I don't know how much would be too much, so all I can say is that it's too much if it looks like the build-up is so fast that water would eventually begin running down the sides,  I know that this is obvious, so I'm just saying that I don't know if it would be dangerous at levels lower than that.

 

I dunno... I'd be scared to do this to be honest.

The purpose of the airtight box is to lit the amount of water that can condense. There is only so much water that is in the humidity in the air contained in the box. Even so there may be enough to cause problems, so I'm looking for ideas to remove/lessen the humidity in the box or insulate the parts. Any ideas i would love to hear, thank you.

What about the computer itself though?  I mean, what about the waterblocks and the tubing that has to run through the computer case?

Okay, so the idea you have going now is, an airtight box, chilled from the outside by water, which is being cooled by water, now whilst water is much better than mineral oil at transferring heat, unlike the mineral oil system, the water would not be as efficient in this case as it is no in direct contact like mineral oil would be, now with this system, I can say with a confidence that this would not cause condensation, it simply would not cool the system enough, and to build this would be expensive anyway!, I think with your limited funds, you would be best of either, a mineral tank, not airtight, and just have it mineral oil circulating to a radiator, this is what is most commonly done with mineral oil cooling no problem of condensation, or, instead, set up a standard water cooling system, stick a heat sink on the cpu, maybe gpu also, set up the system there are many guides on the net to help you along, throw in a few fans, and away you go smile.gif, i really would urge you not to try this new idea, I am under the impression this will be the only source or cooling for the rig? If so, bad idea, with no air ventilation, and the only way for it to lose heat, is in contact with the walls, it would not be very effective, the surface area of the container is simple to small and in effective, much better to have this water cooling directly on a heat sink over the cpu, with limited funds especially no point experimenting and risking your cash, go with the tried and tested, mineral oil to a radiator circulating i would advise first, then if not, a water cooling system smile.gif Any further questions happy to help smile.gif

Okay, let me clarify. I'm going to have a water chiller which will chill the coolant to -10 (probably at water/ ethanol mix). Then the water is pumped to the CPU block, gpu blocks and then to a radiator within the box that chills the inside of the box.

How would a fan like the ultra kaze handle full submersion? I plan on doing a scrap build and would like to use one of those to disperse heat and circulate oil.

Not sure if this thread/idea is dead or not, but I have experience with both oil and chilled water cooling. I can say that oil is a mess to work with, and not worth the hassle over just condensation proofing your stuff. I am currently running a chilled liquid (80% deicer window washer/15% antifreeze/5% biocide) build that ustilizes a 8000btu AC to chill the liquid. It cools it to about -30C or so, then I pump that through waterblocks. I run constantly for extended periods of time (weeks sometimes) and with the proper amount of condensation proofing, have never had a problem. An airtight chillbox, while great if built correctly, is HARD to build, and any leak could lead to internal condensation formation, or with the water submersion idea..instant pc death. I'm not sure if you planned on still trying to use the mineral oil as a dielectric (a means to keep condensation from forming) but one thing to consider is that your water blocks WILL chill the oil (taking away from AC's total chilling power for your blocks), and this will cause condensation to form on the surface of your mineral oil (as it will reach a temperature lower than the room temperature). Given enough time, this water could saturate the oil and possibly cause shorts. I have first hand experience with this. While a water/oil emulsion is still an insulator, unless sufficient stirring is given phase separation of the mineral oil and water will cause local pockets of water to form, which will lead to shorts. As for fans moving oil....if the temperature of the oil is high you will have no problems, however, at temperatures below the working temp, it becomes exponentially harder to move. I was using full synthetic polysilicone oils that had a working temperature of -20C, but when the oil reached the low temperatures it COULD NOT be moved by a fan. I even ordered a 4amp 75w fan (moves 900cfm, while most pc fans move 40cfm) and that could not move the oil. If you are still actively pursing this let me know, I've had a bit of experience with this and know a few things that work, and many that don't.
