Connecting cooling fans to cool filament

[Anehall]

Hi!

Trying to connect cooling fan that cools my print while im printing... got a Geeetech Prusa I 3 Pro B acrylic with gt2560 mainboard... On that board i got:

Fan1: Extruder1
Fan2: Cooling mainboard
Fan3: Suppose this is for cooling down extruder 2 if i plug one in

So how am i supposed to connect fans to cool the prints down? There is an option in repetier to control fans but not sure how that can work if i dont have a fanslot on the mainboard?

Thanks

Hi,
You don't have a PWM fan port like the following pic shows?
