Hello lads,

I'm facing some odd fan issues here, let me explain...

I'm using a Sapphire 7950 crossfire setup with:

1x Sapphire 7950 with a 810 MHz Core Clock
1x Sapphire 7950 OC edition with a 900 Mhz Core Clock

When i am overclocking these two cards to let's say 1150 Core Clock and increasing voltage to achieve it, the normal (810 Mhz) card is getting warmer than the OC edition card (900 Mhz). That is explainable due to the higher voltage needed for the slower card (lower voltage on default). Therefore, i want to run the 810 Mhz card on the bottom and the 900 Mhz card on the top of my setup. (Top card is always hotter than the bottom card)

Now the odd thing happens.... When i put my OC edition card on the top, the card seems to be on 100% fan speed on default. When i start-up my Windows, the card is always on full blast until MSI Afterburner kicks in and sets the fan speed. However, if i switch the two cards, this issue wont happen.

Does someone know what might be wrong here? The card itself works flawlessly, its just the fan that screws up... Would flashing the OC edition card with another BIOS be any solution? Is that even possible? Could i use my normal edition BIOS for example?

Any thoughts?
