The first and most common danger is heat. Components in your computer is running higher than the rated parameters of the time, it will generate more heat. If there are no adequate cooling, the system may be overheating. However, overheating is not a general destruction of the computer. Scrapped as a result of overheating of the computer is the only case over and over again trying to run on your computer is higher than recommended temperatures. We should try to curb the growth in 60 C below.

Another “dangerous” is that it may reduce the life span of components. Imposed on higher voltage components, it will reduce the life span. Minor upgrade will not cause too much impact, but if it intends to carry out substantial over clocking, it should be noted that the shortened life expectancy. However, this is usually not a problem, because any over clocking people are not likely to use the same parts of four or five years old, and parts can not say anything as long as the pressure will be not used for 4-5 years. Most processors are designed for maximum use for 10 years, so in the minds of over clocking, the loss of a number of years in exchange for an increase in performance is usually worth it.
