I've been regularly using:
echo low | sudo tee /sys/class/drm/card0/device/power_profile
I've am also using psensor to warn me if the temperature rises above 92°. When 'idle' the temperature is at about 80°. If the CPU is used (merely starting eclipse and letting all the the startup validation processes finish) it quickly rises to 88°. If the usages is sustained (rebuilding a java project) the temperature oscillates between 95° and 98°. If I do anything else that adds to the load (ie. if the temperature is >98° for short period of time), the system freezes, but the everything remains on, fans and CPU temperature stays up. I need to turn off the notebook by keeping the power button pressed.
Note that this system overheats /with/ the low power profile.
Here are some general stats about this system, please let me know, if I can provide further information:
