Does this work? Can a computer really function normally while submerged in mineral oil? Would it provide adequate cooling? Seems like a cool idea, but I’m suspicious.

Check out [their page](http://www.pugetsystems.com/submerged.php) on their site about it. They have temp graphs and updates and stuff.

Yea, it works. But for how long, I don’t know. Maybe after a few months or years the oil would eat away at something. Also, changing cards or whatever would be a bitch.

Oil is a very good electrical insulator, so there’s no problem there. However, I wouldn’t be surprised if there were long term problems, like some plastic bit dissolving or swelling in the oil.

Hell, I’ve heard of similar attempts, using high-purity deionized water. It works, until the water picks up enough solutes to become conductive (though I can’t find a cite). [Here’s](http://www.octools.com/index.cgi?caller=submersion.html) an example where people used the more exotic (and expensive) fluorinert.
