push/pull is pointless for that I think... your cfm wont change much with both fans... your rad wont have that much restriction... You would be better having a double size rad either to double/triple the restriction (then doubling up the fans) or doubling the flow (fans in parrelell).

Look at some of the pH has done with fan stacking and airflow. Running push/pull configuration actually DOES help airflow. How could this be?
Let's put it this way:
Your brand X 12cm fan touts that it pushes 50cfm at 22db. Placing one on top of the other will not help airflow (practically speaking). We all know this. HOWEVER, your radiator, regardless of its design, will restrict airflow. If using a 1" core it might drop your airflow rate 30% (ballpark, depends on FPI) meaning that your fan is only pushing 35cfm. If using a 2" core it might drop your airflow by 60% (ballpark again) meaning that your fan is now pushig only 20cfm. If you have one fan that is pushing, adding a second fan to pull will create an area of low pressure on the opposie side of the core. This area of low pressure assists the pushing fan in blowing air through the radiator. Hypothetically, I'll say this reduces the airflow drop by half, meaning that a 2" core will drop your airflow rates by only 30% (ballpark yet again).
Clear? :shrug:
