In short, user reports have cropped up revealing dead Ryzen 7000 CPUs that melted in their sockets due to SoC voltages operating at unsafe voltages (which is specified as anything over 1.3v right now), and bugs surrounding AMD's CPU temperature control system, which can cause Ryzen 7000 CPUs to go a beyond its safe thermal specifications.
I have had no further issues since rebuilding with a new CPU and mobo on April 23rd and updating to a new BIOS on April 28th which locked SOC voltage at 1.3v. EXPO has been enabled the entire time.
Still waiting on the AGESA update.
On the bright side, AMD is reportedly testing a new 1.0.9.0 update internally that is rumored to have all of these fixes intact, but this still means Ryzen 7000 users could be left waiting months for a complete fix.
It is what it is. I'm not going to not use my PC.
