Your radiator cooling fans should run constant if ac is on. But if its not on they will only come on when engine temp rises and they will shut back off when temp drops back down to normal range. If car is not over heating I don't think there is a problem with them only coming on for a short period of time. That is if ac is off. Mine does the same.
