Fan set up...Please Help!

So I've tried working it out online and can't seem to find the answers I need.
My tent is 2.4mx2.4mx2m
What sout of intake fan do i need? I have an exhaust fan that is 800m3/h
Is this too big?
And what is the best way to set up the ventilation system.

More is always better ventilation setup depends on few things kind of light and hood. If it's air Coles hood have it sucking the air from the light creating neg pressure

Running 4x 600w lights and using a fan for heat circulation. Hoods don't have coolers.
