3900x super hot , gigabyte z570 master , vcore auto voltage.

MY 3900X Would often go well into the 80's while pushing well over 1.4v. ive put a voltage offset of -0.100v so it sits around 1.3/1.35v most of the time while being a lot cooler.

You would think that AUTO is the safe bet , no over clocking etc , a base to start from .
Setting the Vcore manually to the same value ( 1.2v ) you would think gives the same result , but increasing the voltage the 1.25v gives a better and cooler result to autos 1.2v , So AUTO may be adding a positive offset value somewhere else.

I've found that on auto cpz says the idle vcore is 1.42 volt , So manual 1.2 and manual on vvc to turbo keep the vcore at 1.2 v full load.
