Anyone else watch TechTV? I just started watching it the past few weeks, we got it with our new digital satellite service.
One of the awesome shows is The Screensavers, all about computers. It’s an hour and a half long. I realized it was going to be one of my favorite TV shows when last week they did a full 1/2 hour on IDE. (Maybe they should’ve called it “GeekTV” instead of “TechTV”, lol).
The other night they did something super cool (multiple meanings). They overclocked a P4 3.06ghz chip by more than 50% to over 4.09ghz! It was running Windows, and it was stable! They cooled it with liquid nitrogen. It was so cool… they welded a 2" wide copper pipe on top of the heat sink, and just started pouring styrofoam cups full of the juice in the pipe. Here’s the link, Cooling with Liquid Nitrogen. When you’re done reading, check the related articles on submersion cases… they did that on an older show I never saw, but it looks awesome. Essentially, they built an aquarium for the mobo, cpu, etc. and filled it with a liquid called hydrofluoroether (HFE). It has a high rate of heat transfer, and doesn’t fry electronics. Then just use a pump to run it out and through some copper tubing in another reservoir, then throw dry ice or some other cooling agent on the tubing.
I guess none of this is really practical for your desktop, but it’s still freaking cool.
