why not use dmidecode ipmi,? things like that?

Especially on a server. Per core temperatures in linux for Zen2 is done using (a very up to date kernel with its k10temp module). Alternatively one can look at: https://github.com/ocerman/zenpower.git I don't know if it works with the c8 kernel (but it does not work with the c7 one). But in the end. Why care about per core temperatures? Setup basic monitoring of the server using ipmi or whatever the vendor supports. /Peter K

Especially on a server.Is it due to some security issue ? We install on all our machines (servers/desktops). thanks. --- Lee
