1. to prevent breakdowns

2. to keep it cool

3. to prevent system failure.

Computer cooling is required to remove the waste heat produced by computer.:)

This is a very common and comented problem especially with core quad and more. 

Esencially you need a great cooling so your CPU-s and Ram dont burn the motherboard out of overheating by its natuaral work. 

If your CPU-s are overheated they dont performe well, eventually your BIOS will shut down the system from preventing furture damage when the temperature of your CPU's reach a certain temperature.

For me top preventation is a question of either the manifacturure if you are using AMD or Intel core and the way the configuration was assmbled. When being configured people should have in mind the overheatting and have aditional external fans, or wiquid cooling systems.

The BIGEST PROBLEM IS that most fans are maid in China and cost2$ but sadly the quality is al so very poor.

A system consist of processor,many IC chip set on motherboard. Each IC in system is made of more than thousand of transistor which produce heat while its operating.

Transistor has switching characteristic which help in producing digital data0 &1.

ON state produce digital data1.

OFF state produce digital data0.

Heat is a important factor which affect the Processor operation,IC operation and even cause burn in ICs. 

So cooling is more important

like humans who when working, running produces sweat which is as a result of heat generated between the muscles. most often they need water  so as to keep them cool so that they can have resistant to continue running or working.if the body fails to produce the heat generated the individual might not have the energy to continue running or working

so it is with computers, because they perform multitask within seconds they produce heat and therefore need cooling to keep them working for longer hours if not most firmwares and hard wares on the motherboard may be damage. like cpu, ic, etc

it should be noted that overheating kills computer systems faster than any other fault

Like any device require power, the power is converted to heats, and so high temperature require cooling system ! Specially for old systems with big CPU dies built using big process like90nm for the P4.

  • Due to smaller and smaller circuits inside of faster CPU's, increased the heat means need to cool down from overheating and burning out the tiny components
  • If a circuit heats up it becomes slow, so to increase the speed of a computer. Without a proper computer cooling system, the PC's electronic components may not be able to function optimally and the integral parts could even be damaged.
  • Overheating can reduce the lifespan of computer components and peripheral units and can lead to data loss and damage.

Because it is the manufacturer's recommendation 

To avoid damage of  the computer 

To avoid loss of data as a result of damage to the computer

  • Dust acting as a thermal insulator and impeding airflow, thereby reducing heat sink and fan performance.
  • Poor airflow including turbulence due to friction against impeding components such as ribbon cables, or incorrect orientation of fans, can reduce the amount of air flowing through a case and even create localized whirlpools of hot air in the case. In some cases of equipment with bad thermal design, cooling air can easily flow out through "cooling" holes before passing over hot components; cooling in such cases can often be improved by blocking of selected holes.
  • Poor heat transfer due to poor thermal contact between components to be cooled and cooling devices. This can be improved by the use of thermal compounds to even out surface imperfections, or even by lapping.

Hello,

 

According to Joule`s law, when a current is passing through a conductor, this creates heat.

A heated conductor is capable to let less current to pass through.

In our case, computers requires cooling in order to: 

-increase performance

-to prevent system failure

-to prevent melting internal parts like CPU which can reach over100`C for modern ones

- Removing the waste heat produced by computer components.

- Keeping the components within permissible operating temperature limits.

- The size of the PC can be a main thing for heating or cooling.
