Make sure your air flow is forced over the CPU. Air takes
the path of least resistance, so e.g. opening the top
of the case will make the air escape. The fans should
be ducted to go directly over the heat sink, there will
be foam or something to make this happen. Operate with the
case closed.

run e.g. lmmon to see your temperatures. I don't know
how to do this with amd, with intel xeon, there is on
chip sensor on smb.
