So, here's my situation, I recently picked up a Sapphire Radeon 7970 OC edition
on Newegg for $449 to replace a pair of 6950's I had set up in Crossfire. Card worked out great and I can easily OC it to 1100/950 and get a bit over 650 MH/s out of it at a decent 73C. I decided to pick up another one and Crossfire them and get some extra hashing in.
I have a MSI Big Bang Fuzion board that has 3 x16 slots in it, and this is my main machine, so everything has to stay tucked nicely in the case. So, with these 7970's, the fans are mounted on the side of the fan enclosure, but the enclosure is a bit wider than 2 slots, so if I try to Crossfire them, the 2nd card blocks the intake of air on the 1st and it shoots up to 85C+ in 10 or 15 seconds and appears to want to keep climbing even at 100% fan. I've tried to put them in the 1st and 3rd slot, but the dang distance is longer than the 100mm Crossfire bridge they supplied will reach and I can't for the life of me find anyone that makes/sells any bridges bigger than that.
So, anyone know of somewhere that has longer Crossfire Bridges or have any other thoughts?
