Have you tried stressing it using a multi-gpu application to make sure that your xfire is configured properly?

I think it's becasue you need to stress the GPU.

well i noticed it when i was in game. one fan was spinning up and the other wasn't. i just like to be able to set them myself for gaming. i haven't really seen a card yet that does the job right it self and with crossfire i like to have the control. i'm trying to learn the fan curve settings in msi ab now. thx for helping me out though.

Like compuman says, make sure you are in a full screen mode as otherwise only one GPU runs. If you are already in full screen, then you can do one of two things below:

1) In MSI AB, make sure you have the 'apply setting to similar GPU' box ticked. Set your custom fan profile and key bind it to a key. Every time the computer restarts, hit the key to apply the fan profile.
2) In CCC, you will have to select each GPU separately and set the fan speed manually to what you want it to be.

The reason I am saying that you will need to key bind MSI AB profile or apply it every time your computer restarts is because MSI AB fan profile gets overridden by what you have in CCC. So, in CCC if you got fan speed at 25%, then most of the time your MSI profile will get overridden and fan speed will be only at 25%.

Hope this helps.
