Yeah the reviews aren't exactly very good at the temps for 2 cards, especially some saying it's only 5-10 C apart, lets not forget they test in open case in most scenarios. However I can confirm with you in a moderately cooled case (closed) the 6970s in crossfire is unbearable. You'd have to open the case, or sit a fan right in front of it to keep the noise down.
Top GPU hit 100C and 2nd one ~ 76-80C. Noise level: beyond insanity. 6970 in xf needs 1 slot gap or water cooling.
The 6950 however is quieter. you should check out the review on hardware heaven and compare with my results. I think most reviews are being very kind to amd in the sound department.
The cooler on the 69XX is not as quiet as the one on the GTX 5XX, I've tried both. 40% fan speed on amd is about the same as 60-65% on the GTX 580.
The 6950 in XF should be just bearable. and I'm guessing top card will top out near 85-90C.
Been playing a couple of days now with xfire 6950s next to each other. At max load there is a 10-12C difference between the master and slave card (master being around 92C). As for noise, it's not that bad, comparable to my 4870x2 at full load, maybe a little quieter.
I was a little shocked at the temp difference but to be honest I've had no issues and have been gaming a solid 10 hours each day on my time off
I'm monitoring my temps etc via AIDA64 in realtime via the G15 LCD
