Passive 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. The heat source (the processor) cannot be any colder than ambient, and even operating below 100C strains the capability of passive heat sinks.

Cool Chips™ represents an active cooling technology which can incorporate passive systems, but also has unique benefits.

The example shown is for a typical electronics cooling system such as might be found in a computer or in an electronics package in your car.
