Ventilation question I need answering, two potential setups, which one would work better?

1) Carbon filter at the top of the room, connected directly to an extraction fan. Fan sucking air through the filter, blowing air through ducting into an air cooled reflector, ducting connecting the adjacent end of the reflector taking air out of the grow room.

2) Carbon filter at top of the room, filter connected directly to ducting, ducting connected to air cooled reflector, adjacent end of reflector connected to extraction fan at top of room. Fan sucking air all the way through the reflector, through the carbon filter.
