11. Overheating

As power flows through different components of a computer, they heat up. Components include CPU, hard disk drives, graphic cards, SMPS (power supply) and motherboard.

Most of these components work perfectly fine with normal heat. But when the heat grows too high, it may cause system failure or even damage components. That’s why CPU, graphic cards and power supply have their own cooling fans.
