assive cooling technologies, like heat sinks, heat pipes, and fans, are well known, and very useful for moving heat.   They are, however, fundamentally limited in what they can achieve.

Cool Chips are an active cooling technology, which can incorporate passive systems, but also has special benefits. The example below is for a typical electronics cooling system such as those found in a computer or in an automotive electronics package.
