How can I fix overheating and random reboot?

A while back, my Note Pro started having issues seemingly with the battery. Once the battery reached a certain low point (Say, 30%), I would see graphical glitches and eventually it would just force reboot. Over time, it got to the point where anything under an 80% charge would have this issue.

I reseated the wiring inside, and the problem was fixed for a few months. It came back, and now while doing little I receive warnings about the tablet shutting down due to overheating. It definitely was getting quite hot.

I researched what I could, and I've seen similar issues with the tablet which no one seems to have a good solution to. Does anyone have any knowledge of this, or similar, issues that might help track down a solution?
