I am at a loss and have no idea why I would be having this issue at this point. I have 2 Sapphire 5870 Vapor-X graphics cards and a Kingwin 1050w power supply that I purchased from Newegg. I installed everything without a hitch and the fan on the second card will not spin when they are both hooked up to the 6-pin PCI adaptors. If I switch the cards around, the same thing will happen and the fan on the second card will still not spin. I already sent 1 card back via RMA to make sure it wasn't the card. I just don't understand why the fan on the primary card will spin but not the second, and if I take the primary card and switch it with the secondary card the fan on that card will not spin either. I even went out to Best Buy and picked up a Corsair 1000w power supply to see if it was the supply and got the same results with that power supply, the fan on the second card will not spin. I had no idea that 5870s in crossfire need over 1000W. Below is my system setup.
Asus M3A32MVP-Deluxe Mobo
AMD 955 @ 3.4Ghz
8GB G-Skill DDR2 @ 800Mhz
Zalman 9900 CPU cooler
4 WD 500GB 64MB Cache Enterprise hard drives
Asus DVD-RW
Asus DVD-Rom
Any ideas on why this would be happening is greatly appreciated.
Thanks,
