Cooling Chips with Thermoelectrics
By Kate Greene on January 26, 2009
If you could remove the layers of circuitry in your computer and touch the main processor while it's running a video, you would feel its blistering heat, which can exceed 100 °C. Such heat, a natural by-product of shuttling electrons through transistors, can impede performance and even damage the processor in the long run. Traditionally, engineers have used simple copper plates to pull away the heat, and fans or liquid-based cooling systems. But these systems are bulky and can sap energy.
