Overclocking
Overclocking is used by enthusiasts to achieve higher framerates than available parts are capable of. Overclocking is such a big part in enthusiast culture that popular websites such as Anandtech and Tom's Hardware often include overclocking as part of a review. Hardware manufacturers release high-end components that facilitate overclocking. Examples include CPUs with unlocked multipliers, oversized heatsinks or water cooling, and motherboards with user-configurable voltages and incremental bus speeds.
Some system builders and part manufacturers now offer factory overclocking, which is covered under warranty.
There are many hazards when overclocking a computer. When a CPU (Central Processing Unit) is overclocked it will generally run hotter than normal, the additional heat can sometimes stress components to the point of failure. In response to this problem, heat sink manufacturers have implemented innovative solutions in air-cooling primarily based on the incorporation of heat pipe technologies coupled with large-finned tower heat sinks. Alternatively many gaming PCs utilize Watercooling as a means of dissipating additional heat from overclocked components.
Watercooling is able to provide dissipation that is superior to air-cooled heatsinks. The watercooling system can be configured to be either far superior to air-cooling but at the cost of being as noisy, or even more noisy than high-end air cooling (due to large, fast, loud fans used on the radiator); or it can be configured to be about as effective, or even a bit more effective than high-end air-cooling, but far less noisy (usually by utilizing large radiators coupled with slow and quiet 120 mm fans, and quiet, yet powerful pumps.)
