Table 270: Temperature limits of the fan (MTCX PX32 V1.01)
Once the startup temperature is reached, the device is started at the minimum fan speed. The maximum fan speed
is reached at a startup temperature of 16°C. The fan speed in this area is controlled depending on the temperature.
For example, slide-in 1: 44°C + 16°C = 60°C --> Maximum fan speed
The fans will only be shut off again if the evaluation temperature is more than 6°C below the switch-on temperature
for a period of 30 minutes (=overshoot time).
