My question is this...am i able to purchase a motherboard with 3 PCI-E slots and use slots 1&3 to achieve a double spacing between graphic cards??
ATM i have 2 HD5970's sitting on a Gigabyte X58-UD3R (i know, cheapo board, powerful cards...blah blah blah), with only 2 PCI-E slots as i lacked the forethought to get the double spacing (card 1 fan is blocked by card 2 and is overheating). Aside from water cooling, this is my only option. Suggestions?
Have you tried adjusting your fan speeds? In my dual card setup (not as powerful as yours), I set the fans to 80% and my temps keep very cool.
Your method is an option but I'm sure it will not run at x16, x16 more like x16,x8 (or x8,x8) Also, you may have issues with the bridge being to short to connect since they are design to go across two slots not four.
mmmm...8x isn't really acceptable. Well, i have the HAF922, which has incredibly good airflow. And i've even stuck an extra fan (from my corsair ram) to push air through from the end of the card as well.
ATM card 2 will sit at 38c no load, card 1 60c no load. Playing crysis or modern warfare 2 for example, bumps card 2 to about 65c, and card 1 to 96c which is close to the gpu's limit. The fans tend to wind up to 100% themselves when watching GPU-Z, so that won't help...the problem is getting airflow into the card.
Are there any decent double spaced LGA1366 boards out there? Price is not really an object at this stage.
