Look the class in temperature.cpp function setRelayPWM |
That's a good point. While some pc fans can be set for 12v, 7v, or 5v, there's some fans out there that can only drop to 7v.. 5v won't spin.
Out of curiosity though, are you guys using 2-wire fans with a transistor controlled by the arduino, or are you using 3-wire PWM fans, controlled directly by the arduino?
Or are they just the same?
