cpufreq-indicator shows a range of frequency options between 1.60GHz and
0.93GHz. I found that changing cpufreq-indicator from 'Ondemand'
(default) to 'Powersave' or 0.93GHz seems to help the most.
I think my system is using 'Ondemand' as it is supposed to but I thought
it would be a good to add a feature (automatic, behind the scenes and
integrated with the kernal? ) where the CPU frequency is capped when
sensors report heat near critical. Then returning to normal when
temperatures are sensible again.
Here is the output from cpufreq-info:
