I think I fixed it by putting my 5870 in the primary PCI express slot and the 5970 in a secondary slot. However, now the 5870 is pegging the temp threshold...but not quite as bad. The main problem seems to be with the fans. The fan of the primary card is not adjusting with the temperature properly. For example, now the GPU of the 5870 will be 90 C, but the fan speed is only 45% but ONLY on the card in the primary PCI slot.
I noticed if I bump the temp threshold to 91 C, then the fan will accelerate to 56% when the GPU temp hits 90 C. It seems to be working better, but definitely not optimal...especially since I can't resume if the threshold is hit!
Right now the 5970 is staying in the 70s C...while the 5870 in primary slot is giving me problems. Almost seems to be a bug in the driver.
Actually...my computer just crashed. Fortunately Chrome saved my input in the text box. The power cable was melted! It was literally melting into the carpet. So does this mean the problem could be due to a small PSU? I think my PSU is 750 watt.
So now I might have to upgrade the PSU. What other gotchas are there? I want to do this right and want to be able to add another video card later if I want. Any good resources for researching this?
