The various components of a computer system such as the chipset, the graphics card and the hard drive can produce a large amount of heat while operating. This large amount of heat may be harmful for the proper functioning of the system. The heat sinks and the fans are responsible for dissipating this heat and maintaining the safe temperature limits.
