One of the greatest dangers to your PC is heat. Desktop and Notebook PCs generate heat that can be damaging to its components and reduce system stability and performance. With adequate cooling you not only extend the life of your PC you vastly improve its stability and ensure it is always running at 100% of its potential. All components in the modern PC produce some heat but there are several major culprits. The CPU and graphics card produce large amounts of heat especially on performance models. Most come with adequate standard coolers however they rely on good airflow from case fans to work to their full potential. Hard drives produce heat and are susceptible to failure if the temperature around them gets too high. Higher end motherboards when pushed will also produce large amounts of heat.
