The fan will only activate when the car's idling AND when it's hot. If your system overheats, then you got a problem (which would be more likely to be the radiator).
If you want to test it, the best way is in a container of water with a thermometer in it to tell you the temp. It's supposed to come on at pretty high temps though - about 90C
