Considering how hot it gets, I wouldn't suggest anything above 1.275v

Alright, thanks. I wasn't sure whether above 1.2v was super high for Coffee Lake R or something so I stayed way below that.

It's always better to see worst case scenario compared to best case scenario for temps so you have piece of mind when doing highly intense workloads.
