Playing with the settings, if i set the extension to 50% cpu and turbo
boost ON then it will turbo up to 2.00GHZ from 1.30GHZ(when under load)
and still maintain 60-70C during gaming which gives a little extra
performance. Not sure what the sweet spot is yet.

After upgrading to 5.6.0-1011-oem it seems sound is back without the

I can get it to 80C (and shutdown) when the AC is plugged in and

I have traced it to int3403_thermal module.
If I do rmmod int3403_thermal - the thermal_zone3 goes away an no thermal
shutdown is happening.
I can use it as a workaround - but is it dangerous for the HW?
By the way, these are the types I get:
/sys/class/thermal/thermal_zone0/type:acpitz
/sys/class/thermal/thermal_zone1/type:SEN2
/sys/class/thermal/thermal_zone2/type:SEN3
/sys/class/thermal/thermal_zone3/type:SEN4
/sys/class/thermal/thermal_zone4/type:B0D4
By the way, I have only one thermal_zone with mode file in it -
thermal_zone0 (other don't have mode)
If I do:
sudo echo "disabled" > /sys/class/thermal/thermal_zone0/mode
I get: Permission denied
The thermal zones that usually cause the shutdown is thermal_zone3 and
thermal_zone4 (rarely)

If I start thermald service, I still can reproduce thermal shutdown
relatively easily.
What is cryptic is that while I monitor the sensors, CPU core temps are
around 85deg, but when shutdown happens it says that critical value was
80C.
Where does this difference come from? Laptop runs above 80C
