as a counterpoint, my 5950x has been rock solid. I ran VMs under proxmox for a while until i moved those offsite and now the 5950x is my primary computer. I did get a water cooler for the CPU and was very careful about application of thermal paste and such. as best i can remember this machine has never crashed, even under severe loads while in a drywalled shed with a window unit keeping the shed ostensibly at 75F. Think CPU cryptomining, or compiling the linux kernel with --jobs=33 24/7.
