Greetings CaptainLunchBox,
I just ran a stress test on our G750, using FurMark and at ultra settings. My results were as followed: Idle 35c and full load at 84c. Mind you, this is a rough number and can change based on many different things, such as dust build up, heat conditions etc. Please understand that the temps you have may change a tad bit (the same for any other G750's out there). That said, we can compare your notebook and the notebook here and use these temps as a guideline. Further, I think it is safe to say you are in the clear and have nothing to worry about.
As a precaution, just remember to use your notebook on a hard surface, such as a table. Do not use the unit on a place where the notebook can easily build up heat.
Regards and Happy Gaming,
Mark
