Ok, so it is clearly established that a two fan set up of push pull is best but then I would follow up with the question... Is it best to have the fans matched.

Ex: I have 3 Yate Loon med fans pushing through a PA120.3

Should I just buy 3 more identical Yate Loon fans for the top or should the fans on top have a higher CFM rating to create a suction effect through the rad?
