Man, I HAD a liquid cooled pc. My friend comes over, looking at it, while I wasn't around, and tips it on it's side to look at it's insides. By tipping it on it's side, the pump in the cooler ran dry, and seized up. I was not aware of this, and the pc kept running. 15 minutes later, it shuts off. The video card was smoked, and while it worked once with another v card, I put the bad V card back in and smoked the mother board. The good news is, Pentium D stuff is CHEAP now, $65 for chip, and my new v card is better. So, for $250, I'm actually upgrading! The bad news is, I'm right in the middle of tracking guitars for a band's album, and fucking waiting for parts! Here's the lesson. Don't fuck with liquid cooling, and don't let ANYONE touch your shit!
