How Not to Test Your Computer

Though it might seem fun to try, you shouldn't pour oil into your PC case or overclock a CPU to 5GHz using dry ice for safety reasons.

Oil-Cooled PC

Though it's been done before, Tom's Hardware has created their own nifty oil-cooled PC, enclosed in a clear case and filled with "8 gallons of cooking oil to improve it’s cooling".
Indeed, the large volume of liquid guarantees absolutely silent operation - no fans are running. And even under maximum load the three major building blocks remain sufficiently cool: processor, graphics card and chipset.

5GHz Project

Tom's Hardware "set out to squeeze at least 5 GHz from the selected Intel P4" in this classic test.
Finally, by gradually increasing FSB speed from 200 MHz (factory setting) to 309 MHz, we achieved a record speed of 5255 MHz. At full load, taking into account a maximum CPU heat dissipation of just under 175 watts, we recorded a temperature of approx. -190°C on the CPU cooling head

Lithium-ion Battery Fire

Put simply, this is what happens when a Dell, IBM, or any other lithium-ion battery powered notebook catches fire/explodes. PCPitStop decided to intentionally create conditions "in which the Li-ON battery pack would explode inside a generic portable."
The results are dramatic. There are numerous conditions where these fires can occur in real life. Faulty battery packs (driving the recalls), faulty protection circuits inside the PC, exposure to excessive heat, and blunt force are some of the major ways that this could happen to you

The oil filled case has always caught my eye, but I have never heard the results of any 'long term' testing. Electrolytic capacitors like to 'breathe' and I cant help but think that submersion in liquid, no matter how non-conductive would have detrimental effects over time.

Why didn't they fill it all the way to the top? ;P

I would imagine the oil cooling would make things a bit messy when you need to upgrade though. I'm amazed at how one spark of static electricity can send computer components in the trash can, yet submerge the entire thing in cooking oil and you're good to go.

I just have an air-conditioned warehouse with millions of trained monkey's each with their own abacus to handle calculations.

I just put all of my millions of monkeys in a giant vat of cooking oil.

Did they not fill it because it would mess with the power supply?

My liqud-encased linux box has been running continuously in its present container since November 2005. The liquid windows box (identical configuration) lost its power supply about 8 months ago, and I haven't sought to replace it yet, since Widows and I don't play together much. I keep a thermometer in the oil bath to keep tabs on things. Oil bath stays at 101 F continuosly. Interestingly, after almost a year and a half never shut down, there is no dust or sediment on the bottom of the container http://russellware.com/liquidlinux
