Here's something new: PC cooling using mineral oil and a functional T25 turbocharger. While these methods aren't practical, they definitely are conversation pieces nonetheless. Continue reading to see more. Click here for first picture in gallery.
Forced Induction PC Cooling
Spinning at 3500rpm, this T25 turbine from a 1990 Mitsubishi Eclipse is used to cool Raktron's PC. The case is not sealed to prevent pressure from building up, as the goal is to just blow air through the case. Its creator reports that the speed is "enough to move some air without having to worry about the bearings, which are designed to be water-cooled."
If extreme PC cooling is our thing, look into a mineral oil aquarium. The oil is great for absorbing heat without needing to vent to the surrounding air. According to its creator: "after about 2 hours, the temperature settled at a new maximum of 84C on the CPU under load."
