You'd be suprised how well a fan forcing air on the back of the motherboard will help with that very thing. I have a 120mm blowhole cut in my mobo tray with a fan forcing air onto the back of the board. I'd be lying if I said it didn't help my OC on my DFI NF4. Granted, its not as helpful as a fan blowing on top of the board, but every little bit helps.
