I would like to measure the CPU temperature and depending on the value turn on/off the fan using the pins close to the Host USB connector, someone could help me with the code to do that? or directions on how to do that, much appreciated.

From the schematics we can see that the fan power supply is directly connected to the +5 V (with a 39 Ohms resistor in series + some filtering elements).

So unfortunately there is no way to control the fan.
