"is it like using the oil as power?" - HalFTW, on 10/11/2007, -0/+19Mineral oil is not a vegetable oil.
- ByronT, on 10/11/2007, -4/+14Also, a warning: my friend sent me these notices which I believe he found on another site.
Using vegetable oils to cool hotspots like CPUs and GPUs may lead to a slow buildup of a solid polymer layer on the electronic component. This will impede heat dissipation, and lead to overheating. The most likely outcome is component failure rather than a catastrophic failure, such as fire.
Vegetable oils slowly polymerize (turn into a solid, rubbery mass) upon exposure to oxygen. This process is accelerated by higher temperatures. - MaxwellTD, on 10/11/2007, -1/+6it needs some of those fake swimming fish you find at the toy store.
- ssbopper, on 10/11/2007, -0/+5i think the HDD is pretty securely sealed to keep dust and other particles away from your precious data so oil probably won't get in. The fans, however, look like they could have their lifespan shortened considerably with all that resistance from the oil though.
- cramd, on 10/11/2007, -0/+5I wonder why they ran Ubuntu on the "old" test hardware, then XP on the "good stuff"?
Would the oil have any effect on the hard drive? I would think that a coating of oil might cause some issues there, but I could be very wrong.
Very cool in any case (no pun intended, but I will take the laughs anyway) - OpCzar, on 10/11/2007, -0/+3Tomhshardware did it with cooking oil:

- spmyke, on 10/11/2007, -0/+2Very cool. Upgrading would be a pain, though.
- stuntman242, on 10/11/2007, -0/+2I'm guessing the extra load placed on a fan (designed to run in air) submerged in a liquid would cause it to draw an out of spec current (as in amps), and would spell a quick end for the fan.
Perhaps replacing fans with larger heatsinks and using a pump to circulate the liquid would be a better long term solution. - dansued, on 10/11/2007, -0/+2HDD aren't sealed, there is a valve of sorts to keep the pressure equalized. Obviously, this means you can't put the drive under the oil. A good place to hide it would be up under the lid of the aquarium.
- spudnic, on 10/11/2007, -0/+2"upon exposure to oxygen"
Where does the surface of the component get the oxygen from if it's completely submerged? Would only really be a problem if there were air-pockets - nothix, on 10/11/2007, -0/+1this is awesome, never seen this before. Hope to try it soon on a spare computer.

- redskin, on 10/11/2007, -0/+1Liquids absorb heat extremely fast, and the mineral compound they use in the video absorbs and loses heat really quickly. If you check out this video, http://digg.com/videos/educational/Holding_a_water_balloon_over_a_candle you'll see what I'm talking about. I wouldn't count on this liquid causing any problems, even if it did crystallize on the surface of the computers, it should still allow heat to flow easily...
Of course, I'd like to see short and long term clock speeds. - rye419, on 10/11/2007, -0/+1oil is also non conductive, so it won't short circuit anything
just dont put your HDD's or optical drives in the oil >. - SpaceDreamer, on 10/11/2007, -2/+3an aquarium... filled with oil ?
To whoever wrote the title of this story: look up "aquarium" in a dictionary. - JohnC86, on 10/11/2007, -0/+1I imagine it'd slow the HDD down a lot? as the head tried to move through the thick oil it'd be physically a lot slower from the viscoity(sp?) of the oil? Amongst any other problems the oil may cause..
- tonich03, on 10/11/2007, -0/+1It needs one of those Mitsubishi robot fish.
- ByronT, on 10/11/2007, -0/+1Yes you are correct; I did, however, want to provide some sort of sourced caution though, so people know what is possible to happen if they use a vegetable oil or mineral oil, although I'm not sure if there are hazards with mineral oil. Does anyone know if mineral oil can lead to the same thing though, due to a similar buildup of excess material?
- jonbach, on 10/11/2007, -0/+1Original link, with project details and cooling performance readings:
http://www.pugetsystems.com/submerged.php - jordansampson, on 10/11/2007, -2/+2I have a few questions for anyone who knows about this? the oil does not hurt the parts? Is there a particular type of oil you have to use? Does this keep it cooler? finally, why would I still need the fan if its not circulating air? Wouldn't the heat disperse itself through the oil?
- socerdevil25, on 10/11/2007, -0/+0Is there some sort of enclosure around the processor to prevent the oil from getting to it? I can't tell what that thing is from the pictures.
