Default Power Supply Fan Suddenly Stopped

This thread isn't urgent, but I'd be grateful for any comments.

Recently I pulled another computer out of a dumpster. The machine turned out to have some issues, but in the worst case it's still a source of some very useful parts. One of the issues is that the power supply (PS) fan stopped working, which has prevented me from debugging the other issues. Here's a brief summary of what happened:

PS is an Excalibur Retail XC-400B SATA ATX
main connector to mobo is 24-pin, BTX system design

At first, I'm certain the PS fan was working. At one point I swapped out the whole PS as part of my debugging. The same problems occurred with the other PS, so I figured the original PS was likely OK and cleaned it up a bit (removed dust). After I put it back in, the PS fan was not working and the PS overheated somewhat and began to smell a bit (which clued me in to the fan not working anymore).

I suspect the worst, it's just dead or at best intermittent, but I wanted to check if there could be something I'm missing. Is there any way the PS fan could be off due to some kind of configuration issue to do with the motherboard, BIOS, or anything like that?

Thanks for any comments.
