Part Cooling Fan: How to Connect???

I'm using a Ramps 1.4 board with Marlin 1.1.9. I have a 12V fan mounted on my extruder. Which port do I connect this fan to so the firmware can control it? Also, what variable controls it?

How about reading the doc then eventually ask in the proper place ?

I did and this sounds like a personal attack:

D9 is the normal port for the fan.

Its controlled with M106/M107

This is normally auto generated in your slicer.

This should not be confused with the hot end cooling fan, this should always be on on a ramps (as there is no mosfet for it, you would need to add one)

OK, this makes sense since those ports are 12V. I was a bit confused since that port is labeled "Heat 2 , 9" on the PCB.

Thank you.
