Sufficiently generic to the topic. :)

In my experience it's "When Intel CPUs overheat, they throttle down (and
will recover even if overheated to the point of seizing up); when AMD
CPUs overheat, they fry and die." Cutting power is a definite
improvement over croaking outright...

The stock AMD heatsinks are crap. Every damn one I've ever seen is junk,
and at best barely does the job. When I replaced Westworld's crappy
stock heatsink with a solid copper heatsink with more fins and a bigger
fan, its operating temperature went down about 20 degrees. (And the fan
is much quieter.)
This'un, tho I only paid about $12 for it.

Was so impressed I promptly bought another for the other AMD, tho the socket939
that it's supposed to also fit was just a little goofy and
wouldn't seat right (and that board has since died, tho I have another
that may eventually get it as an upgrade).
In fact, when I temporarily used a loose chunk of finned copper with NO
fan (probably started life as a server heatsink), even that worked
better than the stock aluminum AMD heatsink.
I've found AMDs have a more irregular surface than Intels, and
absolutely require thermal grease (or a crush pad) to make good contact
(conversely, Intels often don't need it). The cheap copper-based grease
is the best I've found; with Intels you don't notice the difference so
much, but with AMDs you can tell it's much better than the silver stuff.
