I bought a pair of DuOrbs for my eVGA 8800 GT. I would say this article is spot on, except, noisy? Those are actually a bit quieter than the stock coolers. I suppose the Xbit guys are decibel savers, and run this tests in padded rooms! LOL
I love your reports, but it would be helpful to have a common baseline cooler. You don't include the Thermalright HR-03 Plus in this report, so it's not clear how to compare these results to other recent vga cooler reports you have written.
