You will need to diagnose this properly by checking to see if you are getting power to the fan when the engine is warmed up. I do not suggest replacing any more parts until you do this. You can do this with a test light or a voltmeter.
If you are not familiar with how to perform an electrical diagnosis of a circuit, then I suggest taking it to a shop.
