Yeah, the GPU usually doesn't go past 70C unless I'm playing a high intensity game like AC Black Flag. The CPU however does get pretty hot at around 70-80C, but I've done research on the laptop and part and this is to be expected. I even put the laptop's fans to the max to cool the CPU down even more when I play, and the pauses still persist.
Are you running other programs in the background while in the game? Try running a hard drive check also, not just the checkdisk from Windows, but a full scan from either the laptop vendor or from the HD maker's support site.
