OK her we goe with the dumb questions LOL

I have a 1000 watt hps i got from a friend, and and dont quite understand the duct/vent holes on it. It is glass sealed and has a 4" vent hole on the side going directly into the glass sealed bulb area,then there is a 4" hole on the very top above the reflector. So my question is, would i vent straight from outside into the side hole of the light with no fan then vent out the top into an inline fan and then out of the room, or do i have it all wrong.
any help would be great
