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

Presumably because the bearings are worn out. Get another one.

I've disassembled these, cleaned, and relubed with decent success.

But a new fan is not expensive.



Yes, not nearly as expensive as the possible damage caused by a stalled worn
out fan that soemone tried to bodge back to working condition instead of
replacing it. I'm thinking Power Amps, computer chips, or any gear that
someone has paid you to fix properly.
