You may want to research more into the causes of overheating before you settle on a solution. For example, if like me, you're not running a vacuum advance, the engine will run hotter at idle than it would if the timing were advanced. It's also possible that the fan you have is not sufficiently shrouded and sealed to allow it to effectively pull/push air through the radiator. There may be other reasons why your engine tends to run hot. Good luck.
