enable "layer fan" under RAMPS

in Questions & Answers
Extruder fan is always on, no problem with it.
I would like to place a second fan, layer fan, at output D9 reserved for second struder.

I don't know if I must enable "Enable fan control" or " Enable second fan control for cooling.". And for "Print cooling fan pin": pin d9, fan pin or "heater 2 pin"

I 've tried several combinations and I can't find the right one

    Enable fan control and D9 or HEATER_2_PIN or FAN_PIN. For ramps it is all the same pin number:-) But make sure to have only one extruder so no other function uses D9.
