Hi

linux automatically reduces frequncies, please refer to

Chapter 25 Thermal Driver attached Linux Manual.

One can try to modify the thermal driver to consider a

lower critical temperature, just for example  lowering the temp threshold

of the critical temperature to be 15 degrees by doing:

echo 15000 > /sys/class/thermal/thermal_zone0/trip_point_0_temp

Best regards

igor
