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=3D1... I guess I can write some scripts?
