The CPU is a microprocessor, which is fabricated on a metal–oxide–semiconductor built-in circuit chip. It is often cooled by a warmth sink and fan, or water-cooling system. The clock speed of CPU governs how fast it executes instructions and is measured in GHz; typical values lie between 1 GHz and 5 GHz. Many trendy computers have the choice to overclock the CPU which reinforces performance at the expense of higher thermal output and thus a need for improved cooling.
