Every laptop comes built with a dedicated cooling fan. Hewlett-Packard (HP) laptops are no different. The cooling fan's purpose is to regulate the temperature of the CPU, or processor chip. If the fan goes bad, the CPU will overheat causing severe damage to the motherboard and any hardware devices nearby. This is why it is important to regularly clean your CPU fan. An excessive build-up of dust and debris will eventually cause your CPU fan to stop working.
