Upgrading fans

I'm planning on sealing the closet off. I have a 120MM fan (150-200 CFM) in the room attached to a carbon scrubber that is exhausted into another room that has a vent to the roof.

Would it be more efficient to buy a 300 CFM fan to cool the room or should I upgrade the fan in the ceiling to something more powerful?

Both rooms are about the same temperature and they'll both eventually be sealed 100% of the time besides when we need in there
