passive or active intake for sealed 792cf room?

Should I use a passive or active intake for my sealed 792 cubic foot grow room? I have 2x 1000w lights I have figured out how to exhaust the room I just dont know what method of intake is better to use for a significantly large room passive or active.
If anyone knows please give me a hint.

You need to exhaust the room due to heat issues??? If so, then it is not a sealed room. I have a 768cf sealed room with no intake or exhaust and the only time outside air is introduced is when I open the door to walk in. And I run 6 x 600w HPS in there on 12/12.

But if you need to exhaust due to heat then have your intake low to the ground to bring in cooler air and your exhaust close to the ceiling to remove the hotter air more quickly and exhaust thru a good carbon filter.
