what's the different? I know that sleeve bearing lifespan is shorter than the ball bearing type, but is double bearing means double lifespan than the single ball bearing?

also, does it mean more quiet than single ball bearing?

All recent fans are dual ball bearing. Like fsujustin33 said, it is more durable over long periods of time and it is quieter. If you look at any recent computer fan, their specs will list them as dual ball bearing.

Panaflos are bushing fans and I hear they run a very long time. They are really quiet also.

How about magnetic bearing fans? I'd like to see more companies sell those. They'd be even quieter than bushing or bearing fans.
