Today's computer chips pack billions of tiny transistors onto a plate of silicon within the width of a fingernail. Each transistor, just tens of nanometers wide, acts as a switch that, in concert with others, carries out a computer's computations. As dense forests of transistors signal back and forth, they give off heat—which can fry the electronics, if a chip gets too hot.
