Quite a lot of thermal management is split up into different areas: CPU itself, ACPI, logic board firmware, kernel, and user space. I suggest making sure the logic board firmware is up to date as a first step. sensors isn't a default package. New in Fedora 33, thermald is installed and enabled by default. I'd give that a chance to work (or fail) on it's own without anything else competing. It's expected that thermald improves thermal management, but at least to not do worse than not using it. If the thermal behavior isn't correct with thermald enabled in a default configuration, then the next test is to disable thermald and see if the same behavior still happens. If that fixes the problem, I suggest a thermald bug report. If it doesn't fix the problem, then we need to look at a possible kernel regression. There are some user space tools that can directly manipulate fans if none of the above works out of the box, but I'd consider that a fallback position. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
