Might be: I don't recall you saying.  And I will admit to having a bit
of a mental block with the heat sink and fan assembly being labelled 
"AMD approved".  I interpreted it as being the proper device for cooling
under normal conditions; apparently should have been "it fits".

Probably should clarify that as add I just don't run one thing here at a
time.  Virtual VP was running.  May have had several LibreOffice
documents open because I frequently use for jotting down electronic
notes while working on projects, extracting notes from forums, etc.  But
yes, sometimes a seemingly low key process would elevate the CPU 
temperature.  And sometimes not.

Or maybe "Wild Kid": with the proper heatsink and fan no thermal issues.
Does rise at time, but no where near those dangerous levels as before.
So with that aspect seems to have outgrown its rebelliousness.  Now of 
the USB lock up issue -- that same kid now in the work world and n=knows
to behave during the week and party on the weekend?!

Possible.  Or a mis-shipment: carton/pallet dropped off at the wrong  warehouse.

<chuckle> Not really: he has an older Ham license so AFAIK back then 
they had to know some electronics theory.  I do know there are some
liquid-cooled units out there -- friend in Nevada had one leak.

Possible.

One here was the permanent replacement.  120mm fan in a PSU locked up.
Removing the PSU to get inside was going to be a pain as one or more of
the motherboard connections were under the HDD rack.  Plenty of room to 
attach the replacement fan from the outside and connected the power 
cable to one of the motherboard's fan outputs.

Why am I thinking 'Karma Surta'?!!

OK, now that you've wiped the coffee spray off the monitor do seem to 
recall all of the current (even old but still semi-current) CPUs are 
flat and when I'm replacing the heat sink assembly I do double-check if 
for the right socket: identification and picture.  Only one clip on
either side?  Check!  Room for the unit?  Check.
