I am aware that the fpi of a rad affects the static pressure required of a fan quite a bit due to the restricted airflow. However, does the thickness of a rad make a difference? Surely more surface area = more force needed to push air through BUT ALSO, the air is already going to be moving in...

I have been researching fans and have come across these terms a few times, could someone please explain them to me? I know that they are alternatives to PWM which I know requires 4 pins and allows for variable speeds as chosen by mobo, Just don't know about the two above.
