Unless a review article states: "DB numbers were obtained by holding a SPL meter, set on "C" weighting, 12 inches from the source" I don't even consider the numbers. You need to have specifications as to exactly how that number was obtained. If I put my SPL meter (I have one, it makes setting up HT a breeze) 2 inches away from my FOP 32, yeah, maybe it is 50db. But, with the case closed and me standing 6 feet away, then its' 30db. See what I mean? I have the FOP32-1 w/the YS tech 26CFM fan. It's not noisy to me. I also have two case fans, as well as the little fans on my chipset and vidcard going. What I hear more than anything else is the air "rushing" thru the slot in the bottom front of the case.
