Temperature Controlled 4-Pin Fan /w Arduino Nano

fan_temp_control's Issues

Possibility to integrate another Temperature Sensor to PWM control a different fan

I know this is not an issue but I wanted to ask this question to the creator.
I wish to add another temperature sensor which will PWM control another fan.

Would it be possible to possible to accomplish this task on a single Nano?

Off State Not Functioning

I have built this circuit and while testing, I have run into an issue. When my state is supposed to be off, with 0% duty, my fan still functions. It is definitely at its minimum running state, but if it is stopped manually it will spin back up. I do not want to have any additional power draw or unnecessary circulation as this is definitely a time-dependent project (cooling a PS4 in an enclosure). I believe it is a power leak from the PWM to 12V as I can unplug the ground and still have the fan spin at this minimum speed. Any suggestions?
