I'm confused about where the fan on a prusa i3 is supposed to blow. Is it supposed to blow on the upper portion of the groovemount, because that's what mine is set up to do. What about cooling the extruded filament on a PLA print to make it cool faster? I see many printers equipped with this: [

Is the fan supposed to do this or is this function for another fan? I want this set up to print PLA and would like to know if I need another fan or just modify the fan that's blowing at the groovemount. I have a Makergear extruder.
