Re: got a problem .. need info
top your radiator off, purge air from system using purge vent (if your car has one) then refill again. with the cap off, start the car and see if it starts over flowing.. If so, you pare pressurizing your cooling system because a bad head gasket / warped head surface.
Another way you can tell is make note of where your coolant level is in your overflow bottle.. Fill your radiator. Replace cap and beat your car for a few blocks (LoL).. check coolant level in the overflow bottle. (Just look) if the level has increased dramatically, you have blown your head gasket.

headgasket/ warped head the pressure of the leaking headgasket ( compression of the engine forcing antifreeze into the overfill)

Re: poss cooling system problem. need info
It's normal for the fan to come that often when the motor is overheating. That's not a problem at all.
Are you sure you're using correct coolant? If it's an old coolant it might lose its effectiveness and also, if you're using more water than coolant, the water might evaporate and the car will overheat.
Other than that, whatever else has been already suggested. Try a new radiator cap.
