Tested with the following script:
X=3
TEMP="/sys/class/thermal/thermal_zone0/temp"
echo RUN IDLE
for ((I=0; I<30; ++I)); do cat $TEMP; sleep $X; done
echo RUN HEAVY LOAD
cpuburn-a9 &
cpuburn-a9 &
for ((I=0; I<60; ++I)); do cat $TEMP; sleep $X; done
echo KILL HEAVY LOAD
kill $(jobs -p)
for ((I=0; I<30; ++I)); do cat $TEMP; sleep $X; done
RUN IDLE
