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
