I have in my hands, a Delta AFB0712MB.
It is the stock fan from a Socket 478 cooler - this came from an old Compaq system.

The fan exhibits no sign of failed bearings - when hand-spun it doesn't vibrate or rattle.
But when plugged in to a power supply or motherboard, it just won't start.
What are the chances that a broken wire (internally) could be the casue of this?
I'm not about to rip open the motor sticker because in the event that this fan is salvageable, I'll find a use for it.
So is there any other way to get to the cause of this problem?

I got that right.
I tested it with like 8 different fan connectors.
Can't be wrong

Sounds like it might have burnt up internally. The only way to find out is to tear up the sticker and see whats under there.

But, rule of thumb: If a fan doesn't spin up when you try it on 8 different connectors, it's most likely dead.
