Temperature Based CPU Throttling  
Written by anichols2000 the 21 Oct 11 at 15:09. New
My laptop has insufficient cooling to consistently use the Ondemand CPU governor mode, much less Performance, without suffering from thermal cutout...mainly due to aging hardware that I cannot afford to upgrade or replace.

Solution #1: Temperature Based CPU Throttling
Written by anichols2000 the 21 Oct 11 at 15:09.
A new throttling mode, 'temp', that allows me to switch between the two modes automatically based on the current highest core temperature being reported through lmsensors. If the temp reaches a cutout (preferably a few degrees less than the thermal cutout for your particular laptop....user-adjustable but defaults to 85 C) it drops you into powersave, otherwise it pushes you into ondemand. This way you get the functionality of ondemand's cpu governor as long as doing so won't threaten to turn off your laptop.
