In their documentation, they do show that the cpu sits below 1v when truly idle. Granted it is for a fraction a second but still. They do seem do be a bit eager to boost. My 3600 (pbo+autoOC) sits at around 43c with a 212 cooler when idling at desktop. This is with newest chipset drivers, windows updates and 1.0.0.3ABB on X470 Taichi using the ryzen balanced power plan.

Doesn't amd recommend against this in their detailed brief? Post 9 Their detailed brief seems to address a lot of people's concern with voltage, frequency and temperatures I've read.

Have you installed newest chipset driver? Prehaps this could be of help. https://community.amd.com/community/gaming/blog/2019/07/30/community-update-5-let-s-talk-clocks-voltages-and-destiny-2
