Krunk_Kracker I have the P5N-D and it OC's pretty good, the chip set does get warm even with the Asus supplied fan on it, there are two chips under that cooler, the 750i
chip and an NF-200 PCIe chip giving this board a true dual X16 PCIe 2.0
I solved the heat issue by making a water block for mine, I have resently procured a
Xeon cooler with fan, this cooler is solid copper and big enough to cover both chips
but will need 4 long screws and a piece of plexi to hold it in place
I have not got that far with it yet, do check out go4life's thread about this board
