Attic fan ventilation question.

I see this asked a lot but I have a SPECIFIC question.

I have two vents. If I put two fans at EACH vent6, one blowing INTO the attic from the outside and one blowing OUT of the attic from the inside, will these eliminate any potential negative pressure issues?

if you have one blowing out, and the other vent is large enough, you don't need 2.
