Yes, I have the 9700 Pro fanless.. well, sort of. A lot has gone on since I made this post
Let me explain.
Strangely, over the last week or so, the weather here in Austin has gotten warmer (In January..Hmm..), so my apartment's a bit warmer than usual because I can't justify using A/C in January. As a result, my temps rose from 22c to 27c with my fans on at 5v.
I got some fan isolators the other day that allow me to run the fans at 12v (at roughly the 5v loudness). Now, the case temp is back down to 21-22c. I think the main reason why the case temp is so low is because there really isn't any "trapped" heat. The top exhaust clears out heat from the CPU and HDD. The rear fan exhausts heat from the GPU/CPU. And the two front fans are assisted by the exhaust fans. It's a delightful arrangement, and would recommend the case to anybody. I'm still having an issue with my CPU temps, but I'm sure that has to do with the low-rpm CPU cooler, because the stock cooler was significantly better.
Well, anyway, in the picture you'll see that I don't have any obstructions blocking the airflow coming from the lower two front fans. So, at 12v, there is enough air blowing onto the 9700 Pro keeping it fairly cool. The heatsink plates do get a little warm, not hot. Also, the rear fan is directly above the heatsink, quickly exhausting heat. I don't have a temp monitor, but I'm thinking of getting one for toying around. If I do, I will post my temps for this arrangement. I think that the two front case fans and rear exhaust are doing a nice job of keeping the 9700 cool.
