Why do computer parts work faster or better when they are cooler?
gpt
Circuits and wires are made of various metals, which are conductive (electricity moves through them quickly/easily). When electric current flows through a wire, some of the energy is lost as heat, causing the wires to get hotter. Heat reduces the ability of a conductor to conduct electricity, so the hotter your computer gets, the slower it gets and the worse it performs. Computers that are running are constantly generating heat that needs to be removed. That's why all computers have fans, to keep cool air moving over the circuitry.
