They reference coolers are best for multi-gpu setup, since they blow air out of the case, non-ref cooler blow air in the case making the other cards& cpu heat up more.
Exactly what I was thinking.

I have 9 case fans installed and my GPU fans running at 50% all the time and my PC is silent... Literally silent. You can't hear anything unless you get really close to it and listen very closely.

They are loud, louder than my 4870, gtx 470, and gtx 580. I ran a 6950 and a 580 together and the 6950 @ 30% was louder than the 580 @ 50%. There's a reason why the idle fan speed is 25% for the amd and 40% for the fermis (6950 is too loud ). And yes, @ 60% fan, all three sounded like a jet airliner taking off and drowned out all 18 yate loon fans.

I think yours is silent because of the twinfrozr fans you have on yours. The stock fan on my 6970 is loud. I have 9 case fans and hear the GPU fan when it gets above 45. Its a whiny noise......I cant wait to get mine on water.

Well i guess i'm used to my case fans running 100%, that's why for me 50%fan speed on the gpu is silent:/

Oh well, i'm happy, that's what matters

Furmark 1.9? 100% fan speed, low 70's oc'ed to 940/1400 1.2v
Hey congrats, you might get those temps if you had your case door off and fans blowing at 100% onto your GPU's, but if you haven't tried or experienced water cooling before, I don't think you understand where I'm coming from. 70c and 100% fan isnt loud or hot to you? I havent broken 55c on my GPU's clocked 1000/1500, 9 rad fans at 1000 rpm. So to me, 70c is hot and 100% fan.... well would be unbearable just quietly.

AMD reference cards are notorious for being noisy, its a fact. People dont call them leaf blowers for no reason.

Edit: Put it this way OP, get the cards, try it out, if its too loud for you, go water.

This

On water @ 950c, all gpu did not go above 50c.

@ Erick, you may think that I'm bashing amd with my posts, but I'm preaching my truth based on my experience with three 6950s unlocked. That was not a smooth venture so I have a few gripes with amd. The fact is that all reference coolers suck, unfortunately, amd's are a bit worse than nvidia's. Again, that didn't deter me from amd since they went on water.

If I go with air-cooling, I think I will use the Noctua NH-D14 or whatever is the best air cooler available in November.

However, would the Corsair H100 be a better choice since it's smaller and wouldn't block airflow in the case as much? Would the NH-D14 produce more hot air in the case than the Corsair H100?

Also, which case would be better, the Raven RV02 or the HAF-X?

Thanks.

h100 and HAF-x make a great pair. If you have any plans to water cool your 6970s, then get a custom loop or pieced kit like the Rasa cpu kits.

If you are worried about noise when air cooling, make sure that your room is well ventilated. My biggest problem is that my room becomes fully saturated with heat, and everything runs quite hot. My top card is at 74% fan at 85C and bottom is 80C at 63% fan. Cards have been 100% usage for 15 hours.

That may sound bad, but my current ambient is 30C = 86F. I also have a box fan pointed in my room.

Hurry up winter....
