I'm servicing a Dell Dimension 4600 which is shutting down after about 5
minutes. The next time the PC boots, it gives a warning that the previous
time it shut down was due to a thermal problem. That led me to notice
that the CPU fan wasn't turning. The part number of the fan is 9G180. Inside
the fan housing is a small two terminal device. It measures about 6.3k ohms.
Is this an open fusible link,
a thermistor, or something else?

Thanks for your reply.
