That depends on how your Marlin is configured. There are two settings for RAMPS1.3+, the normal 33 setting puts the fan on D9, the alternate 34 setting puts a second extruder heater on D9 and the fan on D4 which is not connected to anything on standard RAMPS. So long as the firmware is set to 33, you can use M106 to turn the fan on.

Works great thanks.

Does this work if the version is 13?
If it is set to 34, can the fan be controlled by an M code?
