preventing shutting down due to overheating on linux

The laptop I'm currently working on has some overheating issues. Probably the heatsink has come off from the video chip or CPU or something, because playing 720p youtube streams for longer than half an hour or so on Firefox is a sure-fire way to make the CPU temperature go higher than 85 or 90 degrees C or whatever is the threshold in the BIOS, making the machine shut down. Found this hassle-free solution - 
sudo temp_throttle.sh 85
and it will reduce CPU frequency if the temp crosses 85 degrees C. So, if I'm starting a render or something like that which needs to run un-interrrupted by shut-downs, I can do this and do other tasks like running Firefox without having to worry if the CPU will overheat.
