All electronic devices, when at work, produce some amount of heat. Some devices produce more heat than others. One such such electronic that produces a good amount of heat is a computer CPU. The heat that is formed is generally very high, usually well over 100 degrees Fahrenheit, and should be checked specifically in computers which are used for long periods time or computers that are under heavy load.
The heat that is produced in a processor needs to properly dissipated. Heat has a damaging effect on the circuits of hardware and can cause decreased performance of the system.
