No that's pretty normal. It's very high, but that's laptops. Make sure none of the exhaust ports are covered up. Like if the laptop is on your lap it can overheat more since some of the exhaust ports are blocked and will just recirculate the hot air. If you are worried about the life of the GPU (which you should be) I would cut back a few settings, or try capping the framerates so that you aren't overworking the GPU.
I do the same thing with my 1080 desktop. I cap my framerates or use vertical sync to make sure my GPU doesn't overheat, but I also have the added bonus of having a full desktop with tons of cooling and a custom fan curve, but my GPU never gets over like 50C and thats at full load.
