[Core P3 - Confused About Filter and Air Flow.]

I don't get the filter or ventilation. Every pic shows the rad mounted with the fans pushing into the frame, toward the filter, making the filter useless, right?

 

It only makes sense to me if you were to either put your fans on top of the rad in a pull, or mount the fans on the opposite side of the rad and push.

 

Does this make sense? lol.
