To be honest, I just upgraded to the 3600. I would actually recommend an aftermarket cooler for that cpu anyway even stock. The way AMD seems to like to run them hot now is a little disconcerting. I have a Wraith Prism that I ran on my 1700x when it was installed. And under full load stress test, my 3600 is hitting 71 C. Which is ok I guess, but could only imagine what the stock cooler would be like. Keep in mind with my Cooler Master MB511 case, I have 6 120mm fans in that as well.
