Methinks thats gotta be a prototype of sorts. To have a fan/sink system that huge seems more like a placeholder cooling system while they figure out more efficient core design. The hugeness of the fan reminds me of the Geforce FX series. Big and loud(we know how that series turned out :P).
Just either seems fake or a prototype. I don't trust a grfx card without a fan(those cheap cards you see that used to require huge fans, but now only run on a dinky heatsink), nor do I trust a card that requires something as monstrous as that to run well.
Though it still looks cool!
