BJ my tent is 4'x4'x7' and its a piece of shit cheap one from Ebay. No name or anything. I am using a 6" Carbon Filter , 8" Glass CoolTube, 6" 440CFM Fan all of that is being supported on those cheap skinney ass tent poles in the overhead. You would be surprised how much those little poles can support. I highly recommend you get everything inside your tent. I have mine set up like this....Air gets pulled through my Filter then through the cool tube and out my tent to the window exhausting out my window. So no smell of MJ and it keeps my light nice and cool. I posted pics of how my stuff is hanging off those same little poles you got in your tent. Try to keep the Filter high so it pulls all the hot air that rises to the top. Now with your fans....I look at it like this, why would I have 4 fans running low when I can have 1 fan running high rotating back and forth. Dont forget, fans generate heat so with that many fans going at low seems to be an overkill and could raise your tent temps IMO. Hope that helps, if you want I can draw up a diagram for how you can set up your tent, just PM me with all your stuff that you have and I will do it on Paint and post on your thread.
EDIT:"I just looked at your tent pics and it doesnt seem to be sucking in at all. You want to have your tent a little sucked in with Negative pressure."
Peace Bro.
