IssueAfter updating from the "out of the box" version of the bios 0502 to the 2301, after reboot I immediately noticed that CPU cooler started work much louder.
Tested with Cinebench R23 in the multi core test case + HWiNFO found that it is easily reach to 100C. Initial thought was that it caused by a thermal grease on the CPU but replacment of it didn't change the situation. Also during watching on the HWiNFO sensors saw VID bumps up to 1.518V at the same time with Turbo boost. So I guess it is the root cause.

Tried to roll back bios to the 0502 as decsribed in the
rog forum topic but didn't succeed. It passes ok, but after reboot version the same 2301.
I have quite strong suspicious that it is very bad to have so high voltage and temperature of course. So for now I disabled Turbo boost so for now max voltage is 1.158.
Update:
Without turbo boost Cinebench R23 in the multi core test case goes with ~1.056V on the VID and 66C as maximum
The question is it safe to have such a high VID on cores and how to deal with that in the bios config (I'm absolutely newbie about that and always used all auto configs)?
