Magnetic Floating Bearing (MFB)
8025 Magnetic Floating Bearing Axial Fan (Second one down)
Anyone ever heard of Magnetic Floating Bearings (MFB) before? Or is this just some marketing hype. They don't mention anything about them being any more quiet.

Interesting idea, so I hit up the ol' SPCR search. Check this link: http://forums.silentpcreview.com/viewtopic.php?t=10604
Also search for "Maglev" for more hits. I've read through most of the results and haven't seen any listening results, although Ed Ng had a thread where he looked like he was preparing to report on how they sounded. If you are more diligent, maybe you'll find some listening tests. If so, please link them here!

Passive magnetic bearings can only be made stable in 2 dimensions, so you still need a mechanical bearing for the 3rd dimension. In this case, it looks like there is a mechanical thrust bearing in the axial direction. So you don't eliminate mechanical noise, you just have the potential to change it.
How is that? What exactly makes it impossible (or just too difficult to be worth the trouble) to use passive magnets in all 3 dimensions? Please explain -- I'm a curious SOB.PaulShapiro wrote:Passive magnetic bearings can only be made stable in 2 dimensions, so you still need a mechanical bearing for the 3rd dimension.
I think I recently saw that a new DFI mobo,NF4,has a maglev chipset fan-but being small and high rpm it won't be quiet. Once the tech has been around some fan outfit may use the concept to do a real quiet 80 or 120 but not yet. YS tip driven fan tech still has not shown up in a low speed low rpm version. I hunted for quiet fans a year ago for my rig,recently I'm helping someone else do a build and the Quiet fan selection is much beter,as are other quiet parts. In another year, The best quiet stuff probably will be even more evolved
