Support for PID Controlled cooling

Does the repetier firmware come with support for PID controlled cooling? I have my heated bed and extruder heated with PID cooling. I was hoping to implement PID cooling with a fan run off D9 (RAMPS1.4).
Thanks
Andrew

    No there is no pid cooling function for anything. That would require a fan with thermistor. You could do it with a extra extruder that works as cooler instead. Might get some problems with M104/M109 logic since 0 is off and you would need to invert temperature form thermistor so higher values cause more cooling.

    Why do you want to cool a heated bed with temperature control?
