I don't agree. With two fans and two completely separate paths for heat dissipation, it might be entirely possible to obtain acceptable noise levels with the cooling system pictured. Obviously, we won't know until the card is actually reviewed. But I believe there is a chance for acceptable acoustics.
What's acceptable? I believe it will be a tad quieter than the R9 290, but not near the reference 780 cooler.
I'm really interested to see how it does. 500W is no joke, but I wouldn't be surprised if the 1018mhz clock is misinformation. I could see this thing doing 900mhz at 375W if they cherry bit chips and under volt. If they really clocked it higher than 2x290X then its going to be a heat machine. Can't wait to read the reviews.
FWIW, I think this thing is going to be insane on an EK block and a proper loop. I look forward to seeing what people do with it.
