I have 10 Proxmox servers to maintain all are basically the same, AMD FX 8350 CPU and asus motherboards with several more servers coming soon. FX 8350's are known to run hot and stock coolers weak per web searches. AMD just released a new wraith Cooler to help this issue. Time to figure out if there is a issue and how to fix it if there is a problem.
Testing (this should work on any debian based system)
sudo apt-get install lm-sensors (a program to check system sensors including temp)
