If you're going to spew misinformation at least be well educated so you think about your comment before posting.
Also take a look at what you're posting here. You're comparing a reference Nvidia card versus an aftermarket 69xx. Also referring to the reference 69xx underneath the aftermarket with 34dba, you must keep in mind AMD blows at creating stock auto fan profiles. My 6870 wouldn't ramp past 38% in Metro causing temps to skyrocket near 80C. The 570 ramps much faster and keeps the temps much more in line with reasonable temperatures.
But if what you want is a loud and hot card then by all means gets the 69xx series. And this is coming from experience. Past 50% fan speed I could not take the 6870. 50% on the 570 barely makes a whisper. This chart obviously doesn't depict a card that was under load for more than 5 minutes. Otherwise those AMD card would make the testers ears bleed.
Also just so you know 570 non-reference designs have upgraded VRMs.
I've pushed my voltages way past 1.35v with my 5850 on air and 1.4v on water. No issues as yet. The issue is if you use OCP it downclocks your card everytime you put in under heavy stress, pretty annoying from an overclockers view.
That may have been the review for the Twin Frozer but you can see the sound level is exactly the same as the Reference cooler.
80'c Is fine for a graphics cards core to run at, the 6870's will be fine up to 100'c. Your 570 fan ramps up faster making it louder at lower loads. Using more power, creating more heat and creating more noise compared to a 6950.
Its unlikely that after 5 minutes of load a 6950 will ramp up much higher, if anything at all.
Those tests are performed using a Bruel & Kjaer 2236 sound level meter (~$4,000). Its likely these guys know what they're doing.
Past 50% fan speed I could not take the 6870. 50% on the 570 barely makes a whisper.
Maybe the two graphics cards use two different fan controllers and fans? You've already stated the 6850 doesn't go over 38% anyway, so that shouldn't be an issue.

Besides, I've had my 'fun' with ATI/AMD drivers with my HD 5770.
Got a GTX 460 coming tomorrow
Me mad? Ha.
I own a GTX460 1GB Cyclone OC edition (Probably one of the best GTX460's). Sadly its a heap of rubbish. The thing wasnt even stable enough to play video's with the latest drivers while I was trying to use it last week. Took hours to get sorted and at the end of it would still constantly crash in games. Nvidia's drivers aren't quite as good as everyone seems to think, I've used multiple Nvidia cards. I've got a friend with 460 SLi He's had endless issues with the drivers.
Enjoy your card.Edited by Willhemmens - 2/28/11 at 4:01pm
