P.S.: -- set a Ratio to PWM:
MAX_THERMAL_TEMP            = 50
MIN_THERMAL_TEMP            = 40


These are the maximum values that I have seen, at the moment, the Casing temperature reaches +37С
By the way, I did not use a thermal conductive silicone pad, from the heatsink kit,
between the microcontroller and the heatsink only thermal grease.
I plan to install a thermostat on the basis of DS1821 (in thermostat mode),
connecting to it the exhaust fan of the casing,
the hysteresis of which will be 5 degrees Celsius, shutdown +32C, switching-on of +37C,
which at the physical level will protect the heatsink overheating,
in cases of failure of the fan on the heatsink.
