If you use top, you'll see the CPU idle % presumably go down during the
movie watching, and return to (hopefully) near 100% idle when you're
done watching the movie. Assuming that is the case, the only other
thing that could keep the temperature up beyond the time when it should
have cooled down would be that the system is using frequency throttling
and it isn't being slowed down after watching the movie. Since I don't
have a laptop I don't throttle my CPU so I don't know where to see this
info.
