Public bug reported:
I have a skull canyon NUC as my daily driver and the fan is running much
higher than it should, even when the machine is completely idle.
This happened with the 5.3 kernel and also with the 5.4 kernel during
focal development cycle. It was fixed somewhere along the way prior to
release but it's back with a vengeance now.
