Results: Researchers at Intel, Arizona State University, and Nextreme Thermal Solutions and RTI International, both located in North Carolina, have integrated a thermoelectric cooler into a computer chip for the first time. The semiconductor-based device, which uses electric current to move heat from one place to another, cooled a targeted region in a chip by 15 °C.
