I wouldn't brag about those, the fans are running at 3000-4000 rpm. That shit sounds like a vacuum cleaner.
Wrong, I got a shapphire 5870 vapour X here that runs 3000+ rpm and its noisy. I have loads of shapphire 5850 extremes and they are all set to 100% @ 4400RPM and they are WAY QUIETER than the single 5870 doind 4000RPM. 2 rigs of 4 all on 100% and there quiet. YOu forgot that theres many types/makes/qualities of parts, and fans are a gulf of different ideas.
On topic, the 5870 does 1010/300(no volt mod) and all 5850's reach 1000/300@ 1.93V except 1 which is VERY close. THe best does 1015/300 @ stock! Its a crazy card but it does just that. Highering the volyage on it doesnt make much difference. Seems 1015 is the ceiling and upping the V doesnt matter. Still, 1015/300 stock
i have them all on 965/300 @1.87V mainly, so they last! lol1015 out of a 5830 is very impressive
