6970 Crossfire Cooling - Page 2

post #11 of 26
Do you have side intake fans on your case? On my poorly cooled 600T, my cards usually reach 70-75C with ~45-50% custom fan profile. My ambient temps are 22C though.

EDIT: NM, late post. You already answered above.

I'm in the same boat

My 5870 is crying on me when I play games
But hey, I built my computer knowing it would be loud :x
Solution for me : Put the computer away from my ears (so far that I have to get off my chair on walk a couple steps to give her a DvD to read )

I bet you that you will never see the difference between 16x and 8x slot.
I might be at worse 3% less efficient.

I didn't realize you had a 3rd slot.
By all means use it, the performance hit will be negligible.

Well the way I understand the features of my board is it supports tri fire, but states in the manual that if doing crossfire to use PCIe slots 1 and 2 (which are 16x slots) as slots 3 and 4 are 8x slots. I may have to give this a try and see if I do detect any performance difference.

Check the length of your crossfire bridge.
Mine are too short to do this

Hmm, good question. I will have to check that out before getting to hasty.

will check to see if the bridge will reach later this morning and report back. As long as the only real performance hit will be in benchies, I really dont care.. just as long as my games play they same to my eyes.
