In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.
Graphics card temperatures typically range from 30c to 40c at idle and from 60c to 85c under load. Most high end video cards typically have a maximum temperature between 95c 105C, at which point the system will shut off to prevent damage. A video card is not considered to be overheating until it exceeds 90c under load. At this point, artifacting may start to occur up to the point of thermal shutdown.
Except when I play hd videos the system get gets to 75-80c. I still have not had the freeze but that's because I have temperature monitor to launch SMC fan set at max fan speed when it get a to 80 d. egrees C. I'm wondering if anyone knows the safe temp the 2011 MacBook Pro should be running at When playing hd video.
