I don't think radiators decrease case airflow. They often increase overall case airflow simply because of the vent and fan area they use adds more case flwo. But they do decrease airflow over the surface of motherboard in the CPU area and this can result in higher motherboard component temps. But this same airflow over motherboard problem is increased by tall RAM with foo-foo 'heat spreaders' on components that never overheat with no foo-foo attached to them.
I should have clarified that they restrict airflow given the same number of fans at the same speed.
