My current case is a Cooler Master Centurion, I am forget the exact model but it is a discontinued mid tower, and I have noticed that with the size of my 4870 graphics cards, the air from the single 120mm intake fan does not have a chance to move up through the gap between the graphics card and the drive bays. This means that my current heatsink, a setup with the fan on the side, is not getting sufficient airflow. There are vents above my cpu for an intake for a vertical heatsink, but these do not provide as much cooling. I need to know whether adding an exhaust fan to the rear of my case (I currently don't have any) would alleviate this problem, or do I need to change my heatsink for one with a fan on top?

It wouldn't cost much to install on the back of the case. Try it and see. If not, maybe you can rotate the HSF on the processor.

Is this a common problem? I don't see many cases with intake fans above the gpu.

you could also try to buy more high end fans for the front and back therefore the airflow should increase.....

Antec 900 and 1200 cases, for example, let you move the fans around to where you want them.

I added an exhaust fan behind my cpu and core temps have dropped 10c/

I have a Centurion 590 adding 2 exhaust fans to the top blowholes will seriously improve cooling, it would help advising you if you knew what Centurion model you have in your possession.

I'm not sure, but the exhaust fan at the rear of the case really helped. My centurion is quite old, so I don't know the model # but it doesn't have any ventilation on the top.
