When I launch prime95, the cpu fan turns off. I am running vist home premium, has anyone else had a similar problem?

Also, the fan just stopped now without prime95. I will uninstall speedfan and see if that fixes anything.

Better check that fan out carefully if the problem is not caused by Speedfan.

Your fan is controlled by your BIOS. It will only be controlled by SpeedFan if you have SpeedFan setup to do that. Just uncheck automatic fan speed (in SpeedFan) to let your BIOS handle the speed of the fan.
