Chilled Oil Bath For Cooling Hot Processors

According to a story on, a UK-based company plans to introduce system that are cooled by chilled oil, rather than traditional heatsinks and fans. The idea behind the technology is that oil is a much better conductor of heat than air, and with an adequate design all of the fans can be eliminated from the system...

"It is possible to cut power consumption in half," managing director Peter Hopton told New Scientist. "You don't need to drive inefficient fans, or the usual air conditioning." Hopton first got the idea after seeing computer enthusiasts discuss the idea online. Oil does not affect the function of electronic components and offers a potentially useful cooling solution since it transports heats more efficiently than air.

A number of enthusiasts have tried this technique over the years and it actually does work.  It's the cleanup that's a real pain!
