Nice one bmjbmj. I would still like the OS to not shutdown given there are other options to this problem. A best of both would be really nice.
I managed to clean my heatsink this weekend. Inspection from the outside looked ok, but inside a big dust mass definitely affecting airflow. Now this is shifted, the laptop compiled a kernel at full speed without incident. Heat transfer compound was also added - their strip of tape looked a bit shit. acpitool actually shows my CPU temperature occasionally going to 100C but no shutdowns, on the whole its running 10-20C cooler than before.
