Have you experienced the high temps yourself? I'm planning on getting one, and haven't heard of the fan prob, yet. See you got 8800GTXs, so curious if this is a helper FYI, or based on personal experience? The fan fix is the same as that we had to use for the 4850s(& 4870s) and is listed in here a few times. But all the help is certainly welcomed.
Just wanted to know about the 4870X2 heat issue, man, you'd thought they would have upped the fan speed, or efficiency of said fan, knowing this stuff in advance. oh well.
Oh yeah, minor point, but when choosing the profile and ok'ing it, people need to also unlock overdrive. I had a few email me, saying the fix wouldnt work, and found they hadn't unlocked OD. (You can create a profile w/ it locked, and people may miss this).
