Hey vapor, I think you might be interested in testing the 133cfm Scythe Ultra Kaze 133 CFM version, I find it to be total air noise (no extranious) and @ 2300 rpms it is a big winner in my book. I have no real testing equipment, so I can say for sure, but I would guess a near 95cfm and quieter than any high cfm fan I've ever heard.

Looking at the san ace 4011 ratings I would think that it would be a good contest between the two...
