I built it as suggested (although I added a 1000uF capacitor to the output to reduce the clicking noise of the on/off fan).
But checking the temperature I noticed that it is higher with the fan_motor running, because the fan_motor itself uses the CPU, raising the CPU temperature.
In idle, with the fan_motor off, the temperature of the CPU is about 40°-42°. With fan_motor on, the temperature is about 45°-47°.
I have an heat-sink on the CPU.
I have not yet tested it with a CPU load.
