As far as I know, using ONE cable is sufficient. Also, connecting your cards in PCIe slots 1 and 3 make sense (for lowering temps) BUT be aware :

1. You will get a small performance drop (I think between 5-10%),
2. Make sure you change your settings in your BIOS (advanced>north bridge configuration>PCI express selector>x8 x8) Why? because if you dont, PCIe for slot 3 will default to a x1 bandwidth (ie terrible performance!)

Also, your crossfire connector will probably be too short. You can get one on ebay :

I would recommend using PCIe slots 1 and 2 for MAX performance. If you're worried about temps place a couple of case fans (120mm) directly onto the cards and/or changing the fan profiles in CCC. This should help.

Good luck.

PS Thanks to the members who helped ME with this exact problem.

90 degrees doesn't seem too hot. Consider sticking with slots 1 and 2
