Quick question..... running sli Evga 580's, or at least I want to but with the cards in the x16 slots, temps are too high (90+ on the top card under load) and regular temps on the lower card (high 60's) because they are soooo close together. I want to put the bottom card in the last pci-e x8 slot but the card hits the power,hdd, led pinouts as well as the usb pinouts so the card won't fully pop into the slot. Any suggestions?
