Argh. So v4.9 thermal management does not work.
v4.8 passive thermal management works _too well_, keeping fan at cca
3200 rpm, far below 3700 rpm it can reach. CPU is getting throttled,
and fan is not even running at full speed.
I can manually control the fan with thinkpad_acpi.fan_control=1... I
guess I can write some scripts?
