Identify the Names Purposes and Characteristics of Cooling Systems
Electronic components generate heat. Heat is caused by the flow of current within the components. Computer components perform better when kept cool. If the heat is not removed, the computer may run slower. If too much heat builds up, computer components can be damaged.
Increasing the air flow in the computer case allows more heat to be removed. A case fan, shown in Figure 1-5, is installed in the computer case to make the cooling process more efficient.

In addition to case fans, a heat sink draws heat away from the core of the CPU. A fan on top of the heat sink moves the heat away from the CPU, as shown in Figure 1-6.
Other components are also susceptible to heat damage and sometimes are equipped with fans. Video adapter cards produce a great deal of heat. Fans are dedicated to cooling the graphics-processing unit (GPU), as shown in Figure 1-7.

Computers with extremely fast CPUs and GPUs may use a water-cooling system. A metal plate is placed over the processor, and water is pumped over the top to collect the heat that the CPU creates. The water is pumped to a radiator to be cooled by the air and then is recirculated.
