simple 5v fan circuit. Controlled by any GPIO to turn it on when temp exceed choosed limit. coud be improved using PWM gpio to regulate speed of the fan.

Yes! I am powering my rpi fan depending on the CPU workload using a python code. I wonder how you can get CPU temperature.

i updated the resistances, they were on "k" by mistake. you can find well written python scripts than run at RPI startup. they use "vcgencmd measure_temp" to get the CPU temp. after that it's only code.
