According to current information, there are two main issues: Certain 13th gen chips have had manufacturing defects, specifically oxidation. Also, a bug in the microcode for 13th and 14th gen orders a higher voltage for the chip than the transistors can handle long term, which means especially systems with a high uptime and load essentially burned themselves to a point of constant crashing. They will fix that soon tho, but affected units are permanently damaged now. And no one knows for certain that all issues are fixed now, so I’d advise to either wait for some time (a few months), or go AMD - possibly the new Ryzen 9000s, launching in 15 days (after a 15 day delay).
