What's the big deal if the silencer blows the hot air out of the case, you have exhaust case fans, dont you? I'm using a vf700 on my 9800p, and I'm impressed with its construction quality and cooling capacity. And I have 2 exhaust fans, so I dont need a 3rd one, I'd rather have a better cooler. I havent tried the silencers, but the fv700 by far the quietest fan in my case even on high setting, and I get 440 mhz on the core without artifacts (according to rthdribl). It gets 455 using atitool, but it lies about artifacts, so I dont trust atitool. As far as cooling capacity goes, I'm sure no other air cooler beats a vf700cu.
