[QUOTE="Thunder82, post: 621692, member: 51402"] All current, and a lot of older computers, mac or PC, have these failsafes in place to keep heat from destroying components. Even older G3/G4 macs have this feature. Usually, when a device reaches a certain temperature, it will throttle the speed of some or all components to a very slow speed. Say your GPU runs at 600Mhz normally, if it reaches 70C, it will scale the speed all the way back to 100Mhz. (causing all applications, even your operating system, to run like trash) If the temperature continues to climb, usually the computer will shut itself off to avoid permanent damage. For computers that aren't able to scale processor speeds on the fly, the machine will just turn itself off without warning. [/QUOTE]
