Hi again,

I've just uninstalled thermald manually built from 01.org, and installed the official Debian package as suggested instead.
I've adopted a zero-configuration approach.
Here is my situation by default:

systemctl status thermald.service
  thermald.service - Thermal Daemon Service

NB : indeed I don't have /etc/thermald/thermal-conf.xml but it seems that thermald can work without it (https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1811788).

Logs "CPUX: Package temperature above threshold, cpu clock throttled (total events = XXX)" are still present in journalctl :(

Do you still think thermald can help me? If so what would you try/configure please?
Maybe there is simply something required by thermald I haven't installed yet?

Thank you for your appreciated help :)
