Hi,
The power supply fan draws air in
That's unusual. PS fans normally blow air out.
Also, it doesn't much matter what combination of intake and outtake fans one uses. It actually works a bit better for all the fans to go the same way, but ultimately the back-pressure determines the flow. Where most cases fail is in having too little aperture for the incoming air. However, trying to solve that with intake fans and outtake fans can lead to a situation where there is a closed circuit of air that is not getting to some of the places it needs to be.
One thing that has worked fairly well for me is to drill a whole bunch of holes at the front bottom of the case and back those with a bit of filter material like the stuff used in home heating systems. Then with the PS fan and an additional fan at the top rear of the case, I get a fairly decent airflow over all the circuit cards. Except when fans die, I've never had any problem with cooling. Well, actually I had a Seagate Barracuda hard drive that always ran hot (finally mounted it in the back of the case with a separate fan just for it), but that is not the usual heat problem.
