Yes, and as a matter of fact, on the Asus A8N-SLi board, the two PCI-x16 slots are spaced further apart (2 expansion slots in between them, instead of 1) so that there is room for bigger aftermarket fans and even watercooling on the video cards.Appolyons said:Thats interesting Tommy. I have a question however, what about heat? Shouldnt a PC consumer, like myself, planning on buying a dual sli system soon think about a water cooling system in addition to fans?
