Temperature differential by running air ducts on 1000 watt HPS

i have a room with 6 Hydrofarm SE Hoods that can be vented with 8" hose with glass lenses. During winter if the outside gets up to 40 at night, I pull in air from out side w 6" at 440 CFM and can keep about 80 deg F. When it is colder there are no issues.

So it is getting warmer and during summer the night still get down to 60 F even during Aug.

I am wondering if 8" 745 CFM fan connected to the hoods with 8" house and glass lenses will be enough to keep the room about 82 F. This heat will be vented out and will be pulling in 440 CFM cooler air from outside.

It would be hard to tell being pretty much a constant differential in temps. Sometimes it would be high or low and sometimes it would be on point.
