Hi,

I don't think, that the simple graphics of Mathematica can overheat the chip.
AFAIK the problem comes form a insufficient cooling in the laptop.
You should ask your laptop manufacturer if you model apply to the
problems. But official neither nVidia nor a laptop manufacturer have
confirmed the problems.

Regards
