Fluid Dynamic Bearing (FDB) fan vs (double?) ball-bearing fan: which has LONGER LIFESPAN?

question's in the title

FDB fans are suppose to be the trend

yet...in the end even FDB's just a sophisticated sleeve-bearing fan no?

so since sleeve bearing lasts shorter...does that apply to FDB fans too?

I doubt it matters within a 10 year timeframe, but what matters is getting a hybrid PSU that keeps it off unless youre doing high load stuff.

that's the thing I prefer the fan running (at a minimum speed with a fan curve) regardless of load to avoid hot air buildup

hence my question which of the 2 is more durable - say at equal rotation speed & over a 20y period?
