NZXT Phantom 530 - Push/pull?

Solution
Don't do push pull. The H105 is not thick enough to benefit from it. Push pull only helps when you have a significant resistance such as a heat sink of a very thick radiator. And if you haven't purchased those fans already, don't get them. The fans that come with it give the same performance at the same jet engine like noise. Get the quiet editions if you can, because the performance difference is not something that is worth having a very very very loud CPU cooler. Just run your fans in pull because it is easier to clean and you get the same if not 1 degree off from push.
Let me see if I understand you correctly. On the top vent (or rather below) of the NZXT 530 you want to hang, width-wise, 2 1-inch fans and an 1.5 inch radiator?

Here's the picture on the NZXT site.

Look closely. There is what appears to be a 1-inch radiator installed. I'm assuming the fans are "upstairs" in the cowling. Your proposed configuration would add 1/2 inch to the radiator and another 1 inch for the 2nd pair of fans....

whaddaya thunk? I think mebbe not.
