From a few videos I've watched about it, it looks as though a part in it is not well designed, specifically the vapor chamber. That being said, I don't think AMD has come out and said what the issue is specifically yet.
Anyway, it seems like the vapor chamber gets locked up and stops cooling properly, resulting in temps climbing to 110°, and then the GPU slows itself down to try drop the temps, which fails, so it just keeps slowing itself further.
