dont look at airflow, look at temps. If you put one fna in the middle of that thing, and two on each side, how much better cooling will you have? maybe 5-8c? On top of that, why do we want cooling? That extra tiny boost will only get you so much more performance from the cpu and in games....that will equal out to be about 1-5fps. So will that tornado in your case be worth it? These are the things we much think about. There is a reason why the people that created that tuniq made it that way.
