I wonder if cooling/power is really the key here. I've got a 5950x that ended up getting the water loop I'd intended for my next threadripper - only to find they were not selling the blasted things to anyone but a few companies. With the cooling sized for almost twice what the 5950x could put out, it has been a very stable machine for some crazy workloads. That old dog will likely keep the setup when a zen 5 TR gets swapped in.

For a long time, my Achille's heel was my Bride's vacuum. Her Dyson pulled enough amps that the UPS would start singing and trigger the auto shutdown sequence for the half rack. Took way too long to figure out as I was usually not around when she did it.

I have a 5700X with an AIO water cooler and it runs 65C under load. Never seems to crash. Been like this for years.

My 5950 didn’t like liquid cooling and lives very well with air cooling :)
