Unigine Valley is not as stressful as games are IME. I've gotten higher temps with games like Witcher 3 and CSGO (frame rate uncapped of course).
For CPU tests, I would avoid hardcore AVX testing like Prime95, Linpack and IBT. They're just unreasonably hot.
A lot of people have switched to x264 encoding for stability testing because the temperatures are realistic.
I also really liked the idea behind the ROG Realbench which uses open source programs because it is a realistic test, but I don't know if it's actually useful.
