After repasting my 3900X due to high temperatures, I've noticed that the individual CCD temperatures are a fair bit lower than the overall CPU Tctl/Tdie temperature at times. Under light load the overall CPU temperature can sometimes be as much as 20C higher than the two CCDs, and is generally about 5-10C higher most of the time. During heavy load I find that CCD1 runs a few degrees hotter than CCD2, and the overall CPU temp is about an average of the two. The high overall temps vs CCD temps at moments seem indicative that the IO Die is the culprit here. I'd be interested to know if other Zen 2 users can observe lower CCD temps vs overall CPU Tctl/Tdie? Is IO Die temp monitoring is something we could see in future updates?
