This is how I have mine setup Outlander is dead on with having the fans push air through the radiator. The h100 can even do push pull if you were to push 2 fans on top and 2 fans on top and the bottom. Mind you this is a older photo. I since replaced my graphic cards with a gtx670. Also I don't use the stock fans that come with the unit because the air flow was strong with the cougar pwm fans and they are quite a bit quieter.
