The NF-P12's were good during the winter, and probably adequate now, but I really wish I could find something to get more intake in the front for the summer anyway. I have a fan controller and my holy grail would be to find a fan that I could turn up during the summer where noise isn't a factor (window A/C) and be able to turn it down during the winter without it being loud. I originally had bought 2 GT-15's for the front but I ended up sending them back and replacing them with the NF-P12's. At the time the NF-P12's worked fine but it just seems like I need a little more now. I would need something with good static pressure as there is a filter and a door in the way, although the door has plenty of openings on the sides to allow airflow. I have a NF-F12 on my Megahalems and I've tried putting it in one of the front slots and it sounds like a vacuum and the performance is no better than the P12's. I've come to the conclusion that the NF-F12 just isn't made for sucking air, it's better at blowing air.
Without opening the door and letting the fans vent properly, you're not going to get great temps.
You could shop around and see if a twin pack of SP120's would cut it for you, though I have a feeling my assumption about your current scenario (fans are just too starved for a fresh source) is going to ultimately be right on the money.
It's the same issue that almost all of those silent cases have. Which is why it's better to go with a more open design (like the Arc Midi R2) and just using quiet fans with it.
