Better than some TV shows with episode titles like "203"! (Which was
shown after '207'.)

Yes! LIS some time back, did have the problem of the AMD processor
overheating even though used an official AMD-approved heat sink and fan
combo, Found out later in my 'research' AMD expects their gamer clients
to swap out the cooling unit with a heavy-duty one; so what about us
non-gamers?? Heck mine was overheating to the point of shutting down
just with regular stuff like LibreOffice!

Similar results here: think the critical point is 65°C/150°F. Was
getting close to and exceeeding which caused the immediate shot off.
Once I found out what was wrong (same computer has the random USB lock
up) and swapping the well-it-should-be-good AMD-approved cooling for teh
CoolerMaster one the overheating problem was gone: have seen as low as
88°F; currently psensor indicating 118°F. (I use Imperial Units as
Metric don't click immediately.)
KM> This'un, tho I only paid about $12 for it.

KM> PHKE
Price when I checked was $33 + $8.49 shipping; CoolerMaster is $39.99
and free shipping: I like your $12 deal better, though mine was
essentially free from a friend in Michigan who for some reason thought
the fan was supposed to be attached to the case and couldn't figure out
how to extend the water pipes. (He has to be given some leeway as he is
extremely near-sighted.)

Pretty much the same here: I bought a second CoolerMaster though like
you so far no one showing signs of overheating. A little surprising as
the computer I built using the 'old' CPU from this computer (allegedly
the CPU ran too hot for the motherboard, so got a cooler CPU for this
motherboard and a more compatible motherboard for the old CPU --
confused yet?!) has shown no problems with overheating. -- Knock on
wood!!

<chuckle> So aluminum seems not to be all that good for conducting heat.
I haven't done that but have twist-tied, etc., spare fans to temporarily
take the place of fans which have frozen.

Huh. I know some older processors had some sort of elevated portion so
the heat sink would only properly fit one way. Here haven't played with various
heat sink compounds like you have. For years used a dab from a
small jar of 'electronics' compound -- marketed for use between a triac
or voltage regular or power diode, etc., and its heat sink. Lately
using a silver (?) compound that came with a Raspberry Pi kit -- keep
the small jar at the electronics workbench in the basement and the tiny
syringes of heat sink compound that come with the RPi kits up here.
