No that's not OK!
That temperature is bumping up against the absolute maximum operating temperature and should not be happening unless heavy stuff is underway like rendering, gaming, etc.
Now I want to take a look at Task Manager and see which is the case here.
1. A process (or multiple ones) are going at it and resulting in ~100% processor use.
2. The load isn't near 100% but the processor is still pegged at maximum speed.
(like something near 3 GHz? I know if I let my maximum processor limit sit at 100% my computer and a friend's computer like to idle at max for some reason - but I put my foot down on that.)
