The way you have it setup now it is going to be blowing hot air from inside your case onto the radiator. Some correct me if I am wrong, because that is how I understand it and have it setup.
That's not strictly true. It depends on how you have your case fans configured, and what your internal and external airflow is like. Ideally, yes, you should have it as an intake, but it's rather more complicated than just intake vs exhaust. I have mine configured as rear exhaust, and I get great temps. But I also have two GT-15s on the bottom front, and a 250mm side fan providing a good positive pressure airflow. Plus, the side fan is blowing external air right onto the rad. If I had it set up as an intake, I'd be sucking in warm air from my graphics card and PSU exhausts.
It just depends on what works best for your particular rig. And in many cases, the difference is only 2 or 3 degrees anyway.
