Interesting review Wizzard. I bought this card last week to replace a single GTX 560TI that I was using as I wanted Eyefinity from a single card. The EVGA 560TI was a quiet card compared to my earlier MSI GTX 460 Hawk, that you also reviewed (with Twin Frozr ll cooler)...
I've put all of these cards in to my Thermaltake Level 10GT, even though sound is subjective I must admit that I am unable to hear the Twin Frozr lll cooler over the case fans just like the GTX 560 and yet I was able to hear the GTX 460 Hawk (all at stock clocks), I also tested a stock HD 6950 last week just before I installed the MSI card and I can definitely say that the reference card was louder to my ears during looped runs of Unigen, easily overpowering the rear 140mm case fan..
I would also like to point out that the switch on this card is not the dual bios switch per se that the reference cards have but just a second fan profile, one is set for performance and the other is set for silence. In my testing I have not seen much difference, the silent setting appears to set maximum rpm's at 45% and the performance setting does not appear to have a maximum cap.... perhaps you can retest at silent setting to see if you have better sound results.
I have excellent airflow in my case and even with performance setting chosen, the fans on the gpu never exceeded 51% at the weekend and I was unable to hear the video card over the 140mm rear case fan.
I do like the way that you set out your reviews especially the performance summary. Keep up the good work.
