Here are some pictures to support the fact that air shouldn't be a problem. I popped the fan filter off and this is how close it sits to outside air. nothing but the filter between the fans and the outside, so I would think it would have plenty of fresh air?
it's probably getting plenty of air, but where is the air going? Those kind of coolers expel less air out the back than shroud coolers, leaving a bit of hot air hanging around. If your case is not allowing a consistent air flow around the cards, that will affect the temps. While it would kill the aesthetics of your case, which does look nice, perhaps you might consider installing a fan/grill on the roof above the card, exhausting air. You need to get that hot air out as much as fresh air your feeding in. If not, do you have access to a shroud model, from a friend etc, to try putting in there? i know with my sli setup, once i went to shroud models, my temp issues disappeared. I had ASUS cards with the DCu2 coolers and went with Evga FTW models.
