I recently have situation where my laptop can heat to 105 degrees and shut down. I think shutting down is some bios/laptop internal protection, because it doesn't just gracefully shut down the system, but cut the power off.
Anyway, I wonder if I can configure it somehow to throttle-down CPU if it exceeds some threshold, say 100 degree.
I use Ubuntu 11.10.
It sounds like you need to figure out the reason your system is getting so hot, your cpu is shutting itself off, to protect itself. What your asking goes beyond what software is design to do. If the setting exists it would be in the BIOS but again SOLVE THE OVERHEATING problem. – Ramhound – 2012-05-11T14:23:29.530
In fact it's quite reasonable to run the CPU in overdrive at a low duty cycle to get bursty work done faster. Google uses this technique in their data centers. – joeforker – 2012-06-14T13:57:21.580
