Cooling the computer and all it's hardware is important. This is done by computer cooling methods and techniques which remove the waste heat produced by the components of the computer to keep these components within permissible operating temperature limits so the computer will function normally. Overheating can cause permanent damge to hardware and can also cause fire. Air cooling: -Computer fan Computer fans are used to draw cooler air into the case from the outside, expel warm air from the inside, and move air across a heat sink to cool a particular component. Computer fan types: -Mainly: Axial fans And sometimes: Centrifugal fans -Liquid cooling The water is being circulated by a water pump through a waterblock mounted on the CPU and sometimes additional components and goes out to a heat exchanger, typically a radiator. And the radiator is usually cooled by additional fans. And: -Heat sinks (for comput...
