The CPU was still demanding excessive voltage despite power restrictions. Apparently, Jay recorded a spike reaching around 1.6 volts.

Thanks for reminding me. I checked out JayzTwoCent's video again and if you skip to 13 minutes 40 seconds into the video and play up to 15 minutes, you'll see the yellow voltage test spikes (unmodied BIOS) approaching 1.58V, but the blue spikes (modified BIOS) are reduced to 1.51V max.

I don't think the whole CPU die was getting too hot, just small spots. If I understand Jayz's analysis of the problem, the old BIOS was increasing the voltage on a single core (or possibly two cores) for very lightly threaded loads, to boost one/two cores up to nearly 6GHz.
SInce only one or two cores were overvolted up to 1.6V, there would be localized heating in only one or two spots on the die. If the "best" cores (most overclockable) were consistently selected for boosting up to 1.60V and 6GHz, they would be the cores that suffered the greatest degradation. The other cores would be selected only for more heavily threaded loads, when the voltage applied to all cores would be reduced, to stay within the package maximum power limitations.
On lightly threaded loads, the CPU would remain relatively cool overall, with one or two localized hotspots on the fastest cores. This insidious overvolting would be difficult to detect and took even Microsoft years to fix.
As I've already mentioned, AMD had their own far more obvious hot spot problems on some CPU/motherboards. There was no mistaking a distorted bump on a 7950X and a melted CPU socket underneath. Intel's problem lay hidden deep inside their CPUs.
Whether or not these suggestions of Jayz will be of any use if you have a proprietary BIOS is debatable, but they may help to slow down or stop degradation if you can apply them.

For anyone like the OP contemplating buying a proprietary Intel 13th/14th Gen. system from Dell, etc., I suggest checking VERY carefully to see if they incorporate the microcode fix. This information could be difficult to locate amongst all the glossy brochure ads on the web site.

At my workplace, Lenovo is the main supplier, but I have limited influence over our purchases since my IT manager requires us to buy exclusively from CDW. I decide what we receive, though my choices are quite restricted.
