Why do you always get into eFights with people? Don't you see that? Do you see that others in almost all other cases here don't get caught up in these?

What FPS are you getting? This is a good start.

If you are getting high FPS, use the slider and limit them for the time being. That will reduce the stress to your GPU and then keep an eye on patch notes.

I do get your point, why doesn't Skyrim overheat my GPU and why does D:OS? We can't answer that other than their GPU routines tax your GPU more. However the point of at least a few here is, whatever the game does throw at your GPU, your GPU technically should be able to handle it if it is functioning properly and you are in a properly conditioned room. Otherwise it is dirty, not getting enough cooling or dying.

This isn't the only game that uses 100% of my GPU and I can tell, oh boy does heat pour out of my box even at just 70c. In many cases I can limit FPS to help it out, some games purposely put limiters in them because of this possibility.

There isn't a rule because this game looks so-so it runs cool and because this looks best ever it runs hot. Now ideally it would make sense, but I'd say get used to that never being the case. It is engine by engine, which doesn't have to marry up with knowing generally the temp of your gpu based on how well the game looks on your screen.
