Any hardware that can be damaged by software is defective or is a
specialty machine not for layman use. It was once possible to damage
some monitors by outputting wrong signals from a video controller. But
that was a design defect. No software can damage hardware. Any
processor that would overheat (a slow temperature increase) due to
excessive 'software' commands is throttled or turned off by existing
hardware. This applies to all Intel CPUs even back to 486s and to
newer motherboards for AMD processors.

I have seen many claims. Amazing how many 'computer experts' don't
even know how electricity works. How many don't even know of thermal
protection standard in so many integrated circuits. Many self
proclaimed 'computer experts' will insist they need not know how
electricity works. Therefore urban myths are easily promoted.

Hardware that can be damaged by software is defective by design. And
yet some 'computer experts' also insist that a disk drive can be
destroyed by software. Amazing is how they know this must be true -
without any idea how software talks to disk drives.
