I hope you plan on testing the San Ace 38mm fans at 5v. I think that is where they really shine. I am also curious as to how the Pabst does. I tried it out and 7v was the lowest I could go on it, but man did move some air, not very quiet, but I guess that's the trade off.

Edit: Also, anyway to reorganize the list based on best performance either in noise or CFM?
