M107 will turn off the print fan on D9.
The extruder fan as shown in your image is 12v always on.

Beat me to it

I'm not printing yet, just working my way through the setup and trying to absorb as much info as I can along the way. Consequntly I'm sitting around playing with (working on) the printer that is powered up with fan running. So I became curous about how I could independantly control it.
What is PSU? Power Supply Unit??
I've attached an image from the RepRap site that show where I connected the fan.

You should never really turn of the Extruder fan but just to try a trouble shoot this how is it connected to the Ramps (I Am assuming now that it is ramps?)

I suspect you have it connected to the PSU Input so g-codes won't have any effect on it if that is so.
