best type of processor fan??

[surfactant]

I am using a big 92mm fan on my AMD XP and thermalright copper heatsink. Which type of fan is better, longer lasting and better performing, a dual ball bearing or "sleeve" type of fan??? any help appreciated. Mark

dual ball bearing is better than a sleeve... sleeve's wear out faster.
But I'd take a panaflo with hydro bearings over both of them, because they are really quiet for how much air they push. I don't really know how long a hydro bearing fan lasts but I'm sure it's about the same as long as a dual ball bearing fan.

Ball bearing fans generally last longer, but sleeve fans are generally quieter.

I second what crazydood said. None of my panaflo fans have died in 2 years and all are quiet.
