What is my Computer's Maximum CPU Temperature?
Overclocking is a fairly easy and free way of boosting your computer's performance but there are consequences. For example, when you run a CPU at a higher clock speeds, you will most likely need to increase the voltage to support the higher clock speed. The CPU's temperature rises with an increase in voltage. While CPU's typically have their own fans, there are limits on how much they can cool the CPU. This article is a great reference which lists the maximum temperature a CPU can operate safely at. Of course, different CPU's have different tolerances.
