Air does travel through a radiator. As for the reduction in airflow, that depends on the radiator itself. However, that shouldn't be a concern in most watercooling loops, since the air that leaves a radiator should be expelled from the case.
oh wow i completely forgot i started this thread. lol. so if that is the case, if i had a rad at the top of my case, would air still exhaust effectively?
