    Default So Aris is taking apart fans now...

    I hope he not only looks at the bearing, but also the IC.

    If he could measure the inductance of the windings, that would be cool too.

    I say this because a lot of fans will use the same part number across a wide variety of fans with different parts inside the hub.

    But this is a good start.

    Looks like an exercise in patience to me.

    Silly question, as are many of mine (hopefully not all).

    What makes a rifle fan last longer?

    Last longer compared to what?

    Regular sleeve or you had sth else in mind?

    Regular sleeve.

    With enough oil in reserve, a regular sleeve should last a long time.

    "Rifle bearings are similar to sleeve bearings, but are quieter and have almost as much lifespan as ball bearings. The bearing has a spiral groove in it that pumps fluid from a reservoir. This allows them to be safely mounted with the shaft horizontal (unlike sleeve bearings), since the fluid being pumped lubricates the top of the shaft.[25] The pumping also ensures sufficient lubricant on the shaft, reducing noise, and increasing lifespan." - wikipedia

    So I guess the fluid being pumped is what prolongs the life.

    Where's that oil reserve going to go? You going to have an oil pump inside the fan somewhere?

    I thought it was the other way round, that sleeve fans were OK with the shaft horizontal.

    Nope. The lubricant pools. Bad enough there's more "play" in a sleeve to allow for the pool of lubricant.
