CPU Fan Problems

[Trafficflow]

I am having a problem with a cpu fan failure. I can not get it to work using the
mobo. Can I run a fan off of the psu? Can I buy a controller to operate it also?
What does everybody think?

most of the time if you have any problems with the stock cpu cooler you just buy a new one.

Sorry I was not more clear. The fan is good. Whats happening is the fan will
come on during boot but then it will shut off. I have no idea how to fix! This
problem came up when I changed the mobo and put the old fan back in.
Any advice?
