Hey Rob, did you receive your new side panel yet with the built in fans, how are your card temps?
I did. THanks for asking!
I love the panel and I attached 4 x Scythe DFS123812-3000 "ULTRA KAZE" 120mm fans to it.
I also reversed the front 200mm fan so it was exhausting out of the case.
At first I had the side panel with the 4x120mm fans exhausting out of the case. However, at that point I had 2x200mm fans (one on top and one on front) and the 4x120mm fans all exhausting. The only intake fans were the 120mm in the back and the cards themselves (and I assume the PSU). The temps still rose to > 80C on two of the cards and I decided to reverse the 4x120mm fans on the side panel to be intakes.
That made almost no different, maybe 1C or so, but the two "problem" cards would still run in excess of 80C.
I had the case standing upright, and the worst card was of course in the Device 0 slot at the top, so I decided to lay the case on its side. Still no change.
The only thing I haven't tried is reversing the side panel again to be exhaust, while it's laying on its side.
I'm at a loss at this point, and just removed the 4th card. With the 4th card removed and 1 PCI slot between each of the cards, I can run them at 70% fan, with the side panel fans at 50% and the cards all stay right at 70C.
At this point, I'm suspecting that the cards are touching and the fans aren't running. It's the only explanation I can come up with, but I would think that would cause a lot of noise.
I'm open to suggestions.
