Chilled oil cooling with mineral oil

I have read up on a refined type of Mineral oil used in some high voltage applications for both insulating and cooling. It is called Transformer Oil and has Double the conductivity resistance as untreated Mineral Oil.

There is a fantastic fluid that puts even Transformer oil to shame both in thermal conductivity and electrical resistance, called Fluorinert, But it is expensive

Here is a cool video mentioning Fluorinert and shows the building of a Submerged Mineral Oil PC with a aquarium PC kit from Pugit I think the company was called. The video shows step by step tips for building your Oil rig and they even put the PSU in the tank. But I did not see them add anything to keep the fluid moving.

And this guy has a cool evaporator unit with a coil in a tank that could be placed in the same oil bath with your pc to keep the oil chilled.

I am also fascinated with the Idea of a liquid submerged Rig. I have seen Vegitable oil used and am not impressed, It has an ugly yellow color to it, often an odor and from What I have read must be changed out on a regular basis as the heat from you rig components cause the oil to go bad and darken even more.

I would want the best quality oil or other liquid I could get but I personally would want a nice non-color clear fluid.

With the addition of solid state drives replacing HDD's, that is one less component that needs to remain outside of the tank.

I really like the Idea of starting to not just keeping processors cool but actually start working on actually super cooling well below room temperatures without being concerned with condensation. But then again, the cooler the oil the thicker it is and harder to pump, but I would not think very thin oils like mineral oil would be too much of a problem.
 
I was made aquarium mineral oil pc with PII555 x4 on 3,6 and 9800gt and it was rock stable for more than 6 month 24/7 then aquarium start to leake because oil eat-up silicone that was aquarium was glued.Also i am not satisfied with temperatures.System after four hours of gaming going to be very hot on touch ,about 60C oil temperature,and thats very bad.I think that temperature made silicone to loose and leek.

Tom, would be nice and post a pictures of your system with ac cooling the oil because i am stuck.Sorry to everyone for my bad english.

Fact is oil cooling is a dead end, there is no effective way to keep the oil cool as far as I'm concerned, and what everyone finds is that while it definitely slows down the rise in temperatures, it isn't able to dissipate the heat.

So an idea I have, no idea if anyone as done is maybe use some radiators and pumps to cool the oil?
 
I have radiator and 2000l aquarium pump but for 24/7 overclocked that is not enough.That oil chiller idea is fenomenal but i need help from enyone how to assemble it.Tom say that he done something like that and I belive that is excelent solution even for stronger hardware than mine
 
Liquid helium, compressors, air tight case, bottom mounted release tubes.

He goes down to the bottom of the tank below the Motherboard and releases. The bubbles float up after pulling energy from around them to vaporize. Out of the oil and back into the compressor.
 
Well the system is finally up an running, runs nicely around 17C and I get to OC my 1090T fairly high, I hope to get past 4GHz before I give up on tweaking settings.I'm seeing a massive difference between the core temp on the cpu and the motherboard's cpu temp (It is supposed to be under the cpu socket i believe)While running prime95 torture test at 18C oil running 3.8GHz 1.45V core I get 34C core/29C MB cpu temp. I tried this setting under good air cooling and the cpu temp ran near 60C (the oil uses the same cpu heatsink but oil is forced through it by a small pump rather than a fan)

I'm impressed with any successful endeavour to build a oil cooled rig as it does appear to be a complicated process but I'm a little dissapointed with the overall results as the temps could be fairly easily matched with a straight forward wc loop.
