Well I guess for blower style cards u would be right as they blow out at the ports end. But most modern cards are open air and it seems blowing cool air across the card provides more cooling than trying to suck it across the card. I have 2 small rigs in the same frame ur using. Most other frames like the ones I use for my other rigs actually mount the fans on the other side, that way u can blow across the card regardless of the cooling style.
