I would agree that although they are very expensive and not very attractive the Panaflows continue to be far quieter than any other fan that I have tested.
The TMD fans from YS Tech such as the PD1270155B-2F are the next closest thing. The TMD (Tip Magnetic Driven) design of these fans have the ability to move a lot of air and are popular on heat sink fan combos such as the Vantec Aeroflow. The slim profile of the fan and the center that sticks up a bit do make the use of these as case fans problematic depending on the design of your case, but no matter because they move a lot of air and are very quiet.
Panaflow is most likely your best bet, but do not expect to find them lighted or colored.
The Vantec Stelth fans are also pretty quiet as well.
Those are the suggestions that I have.

True, a sleeved or bushing type bearing as used in electric motors are more quiet than a ball type bearing as used in the same application. The problem with the bushing type bearings is that the factory lubrication over time dries out and then the armature rpm starts to slow down and then eventually seizes. During the time period between when the armature starts to slow down (lower air cfm's) and and when it actuall stops turning quite a bit of heat load has already been placed on the system that's trying to be cooled. Depending on when a user finds out that somethind is wrong with the fans damage can already have been done to quite a few very important components. It's really a trade off on what's important to the user. Top quietness, performance, protection or longevity. I don't think one can expect to have all of them and still have a super quiet fan cooling system.........Mark

It depends on the quality of the design, I have 10-year-old Panaflows here that still work and were used 24-7 almost constantly for over 6 years!
Most of MY Panaflows were pulled out of old XT power supplies!
