CPU cooling

When CPU is active it generates a lot of heat, therefore cooling must be applied to it. There are two main types of CPU cooling. There is air cooling. CPU heatsink has a fan which is part of it, and when air goes thorough heatsink plates it cools them. Another type of cooling is water cooling. It is more efficient then air cooling, but at the same time it is more expensive then just air cooling. It is also a lot quieter than air cooling.

CPUs can be overclocked. Overclocking a CPU means increasing its speed beyond what it was rated at. It is a dangerous operation and can ruin the processor and void its warranty. When CPU is overclocked it requires even better cooling, because it will generate even more heat.
