G752VS here, repasted myself, Kryonaut on die, and MX-4 for all else.
Max if I recall for.. (Running ARK, with no FPS limiter, full 100% benching with no throttle I believe.)
CPU is 65-70
GPU is 70-75
You have double the exhaust though, so unless you're applying too much paste, not torquing the screws enough or fiddled with your fan profiles, you shouldn't be getting into the 90's. Your absolute max should be 85..
80+ is pushing it, and Kryonaut doesn't like hitting 80*C or above.. so yeah, 90 is problematic.
It could be because the 1080 runs hotter than the 1070.. (I always considered the 1070 as the sweet spot, personally.)
You're not sitting the laptop on carpet or on your bed are you? :f
