i have a program that has changed it's behavior to suddenly become a CPU hog (while doing something simple like uploading files for my website). probably a bug, but it got me to wondering how i could limit the CPU temperature to a range well below the maximum that kicks in by the CPU itself. i have an intel processor and it has the MAX which does prevent it from going higher (100C), but i'd like to keep it at 70C or lower. i've been trying to find anything that will let me set this but no luck yet in my searches.
You might try combining your queries with terms for various
CPU-intensive activities such as BOINC, Folding@Home or Bitcoin
mining. I'm not suggesting your task is related to any of these,
but the people who do use these programs face similar issues.
For example, there is the TThrottle program for windows which will pause BOINC calculations when the CPU temperature goes too high. I don't believe that's available for linux, though.
As an alternative, you could try writing a small shell script that works like the following (pseudocode):
STOP_TEMP=70
START_TEMP=65
JOB_RUNNING=1
while true:
cpu_temp=$(cat /sys/something/temperature)
if JOB_RUNNING and cpu_temp > STOP_TEMP:
systemctl stop something.service
JOB_RUNNING=0
elif not JOB_RUNNING and cpu_temp < START_TEMP:
systemctl start something.service
JOB_RUNNING=1
endif
sleep 1
wend
