Super IO Hardware Monitor
Various voltages and temperatures can be monitored by hardware integrated in the SuperIO.
Monitored voltages
3.3V
12V
Output voltage from CX 12V Vin current sensor (OP)
Output voltage from CX 5V STBY Vin current sensor (OP)
Measured temperatures
2 ambient temperatures
Temperature is measured with a thermistor.

Fan Interface
4.24.1
Intel Fan interface
In addition to the two fan interfaces according to Super IO, there is the X2601intel fan
connector on the board which is supported from COM Express interface.
The second intel fan interface at X2602 is shared with X2604. Don't use both at the same time.
Measurement of the tacho signal and control of the rotation speed is done by the Super IO.
