Your Computers Worst Enemy

Heat is one of the main reasons that cause laptop and desktop computers to spontaneously shut down. The first sign is when your computers start to run slower than normal. This problem is usually more noticeable with laptop and netbooks because you will be able to feel from the heat by touching the bottom of the machine. Most computers shut down when the temperature of the CPU is around 70C. Eventually things get worse, to the point where the computer won’t turn on due to component or power supply failure.  

This happens when the cooling fans can’t effectively remove heat from the internal compartment.  Many computers overheat because of their location. Your computer tower should be kept in a cool place with plenty of ventilation for the back of the computer so that the fans can continuously suck in cool air and push out the warm air. Yes, your computer may have a fan but it isn't very powerful. You must keep the exhaust vents free of dust and debris to help provide proper ventilation.

Dust can slow down the fan's rotation, thereby keeping more heat in the computer. If dust settles on the heat sink, it inhibits the heat and keeps it over the CPU. If this cycle continues, you can expect smoke. On top of that heat sink is your computer fan. If dust starts to settle over either on the fan, it must work harder to draw the heat off the CPU. The dust can slow down the fan's rotation, thereby keeping more heat in the computer compartment.
