CrossFireX is causing my computer to crash.

I recently built a very high end computer but I'm having a very peculiar issue with it that I can't seem to fix. Whenever I'm playing Final Fantasy 14, after a few minutes, the game - and subsequently my computer - will crash. Then I have to hold down the power button to turn off the computer. It only happens when I have crossfire enabled. Either one of my cards by itself, it seems to work fine. I thought initially that it was my drivers, but I checked everything over and the only thing that wasn't up to date was my usb hub. I've also checked the RAM with a third-party software and it is fine. I have a 1200W PSU so I pretty sure that's adequate for what I have. Can anyone give me some advice or tips on what to try next? Thanks in advance.

What PSU do you have?

PSU is fine, more than enough.

Check your temperatures, it's likely that the 2 7970's are feeding heat into each other and causing safe shutdown to prevent overheating damage.

My PSU is a Cooler Master Silent Pro Gold 1200W.

My temperatures are fine. My system is fully submerged in mineral oil. The highest temp I've had either of my cards at is 39 degrees.

Awesome, always wanted to do a mineral oil kit.

Anyways, there is nothing majorly evident that could be a problem. Does it only happen in FF14? If that's the case it can likely be chopped up to Crossfire issues. The main reason I moved away from Crossfire is due to the misc issues you will see in a lot of games.

Yes, it only seems to happen with FF14. But fortunately I think I found a fix for it. I made a new profile specifically for FF14 in Catalyst Control Center and told it to run it using the settings for Fear.exe instead. So far it seems to be working. I guess AMD kind of just makes a certain profile for specific games with specific settings and they just haven't made one for FF14 yet. But running it as Fear is working and there's no drop in performance or anything.
