Sunon 80mm MagLev

[Operandi]

"Our state-of-the-art multi-purpose cooling fans actually use magnetic levitation to "float" the spinning fan blade in a magnetic field to dramatically reduce friction, wear, & heat... making these fans run cooler, quieter and last longer than conventional fans!"

Taken from this site selling the fan for $8.95. Sounds like a very promising low noise fan. Anyone heard of this or have experience?
