While I'm not a fan of Tom's either, considering the poor design of early Socket A HSF retention mechanisms it wasn't *totally* unreasonable to ask the question "What happens to the CPU if the HSF comes loose while the system is running?"

In the old days, the chip simply had to accept whatever input voltage and clock it was given, and either it worked at those parameters, or it didn't. Or in the case of a K6-2/400 I experimented on, it worked at 504MHz for a while but became increasingly unstable, and then it wasn't stable at 450MHz, and then it wasn't stable at 400MHz. Then it sat in a workbench drawer two years, and when I gave it to a relative with fair warning, it started working at 400MHz again, and did so for a couple more years. Go figure.
