Anywhere from 9 to 15 volts. At 9 it will run in every other position,
at 15 vdc in the face down position it will still need a nudge.

I've got a small 12V DC .9 Watt 'muffin' fan (1.75"x1.75"x3/8").
It was the cooler for a video card's processor chip and was
frozen up.

I put a drop of oil into its sleeve bearing and it now runs
reliably - almost. It will start every time as long as it is
not oriented with the open 'face' down. (The open face is the
side in which you can see the bearing). If the open bearing is
down, it sometimes starts and sometimes needs a slight nudge to
get it going.

What's going on? How come? TIA


What voltage are you applying to it?
chances are you have a pressed in race for the bearing.
you maybe able to tap it in deeper if you can get to it.
