Ryzen 7 3700X IO Die temperature and sensor questions


Can I check IO Die temperature? I need it in order to make sure that I applied thermal paste properly.
Other than that:
How many temperature sensors has Ryzen 7 3700X CCD? As far as I know there's only one CCD in 3700X.
About sensors:
Is CCD1 the highest temperature measured for CCD chiplet?
Tdie is the same thing as CCD1 right? Only difference is that Tdie is used for fan control?
Die average is average temperature across all CCD sensors?

Btw how can I be sure that thermal paste covers IO Die, and provides enough cooling? I didn't see any IO Die thermal sensor. I screwed up cooler montage and i think thermal paste might not be spread equally. In example it might not cover IO Die.
