Going by past history i doubt it. Said it before and i'll say it again, there has been complaints about reference coolers on these cards back as far as the ATI x1800. And thats going back 9 years now. How long does it take them to take the hint? Its obviously a complex process designing something to dissipate heat that isn't annoyingly loud but they've made claims in the past that turned out to be bs. 6990 was gonna run cool and quiet...enough said about that card, 7990 was meant to be "whisper quiet", review samples for the most part seemed to be, but retail cards routinely hit 90c+ and had droning fans.
Maybe we'll be surprised but going by past history i sort of doubt it.
