I know how to use d9 for adding a controllable fan to blow on my extruded "but" how do I go about adding in a small fan for my ramps. I really want to use a 3rd thermistor to sit on the heat sink for the x driver this seems to be the one that does the most work and gets hot first.
Honestly the heat sinks are keeping things cool enough but I would like that extra protection
Tying to maintain as much energy savings as possible or should I just wire in directly to a all the time circuit wiring in a fan to ramps help
