If the input voltage is below or equal to 13 V, then the maximum supply current to the on-module fan connector is
350 mA. The maximum supply current is reduced to 150 mA if the input voltage to the module is between 13 V and
20 V.
Always check the fan specification according to the limitations of the supply current and
supply voltage.
