Here is the current set up.

So right now there is positive pressure in the case. the reason for that was that my rad use to be the exhaust. but i wanted to make it so that the air going through my Rad was not already polluted my my 7970 crossfire. So i turned the Rad into a intake at the top of my case.This way the air going to the Rad is clean.

So my question is will the positive pressure lessen the amount of air flow through the Rad? Or is the best set up that i can have? Anyone want to add there 2 cents?

Why are the fans and rad there? Too cool off the components. That is the only reason they exist.

Monitor the temps. If they seem high, change something.
Monitor again. If the temps go up, revert. If they are lower than prvious, then you did it right.

they are there simply for the clean air intake. the 7970s run at 70-80c depending on the game i am playing, so i want cooler air cooling my Rad. when they are the exhaust they are using that polluted air to cool the rad

No, that's not what I meant. I was speaking of fans and rads in general.

Does it work in the current config? Of yes, then leave it and don't stress. If it needs a change, then try it differently.

But don't change just for change sake.

Record the temps in the current config.
Change the rad fans around
Record again under similar load. Is it higher or lower?
