Computer cooling (basic information)

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 computer cooling)
 Heatsinks are usually made of a metal with high thermal conductivity such as aluminium or copper, and mainly have fins to increase surface area

-Heat pipes (for computer cooling)

Important:
-Active cooling
-Passive cooling
