PHC vs Chipset. Are they both valid sensor measurements on an AM5 motherboard?

As I was finishing up making sure everything was looking good on my new PC, I noticed some off numbers. I've got an Asrock b650m pro rs wifi motherboard for the Ryzen 7950x. I'm using the NH-D15 without the offset in a 50 litre NZXT case.

First, there is the Auxtin5 which was moving between 103 and 108 c. Another forum said that my power supply would be
incredibly hot to the touch if that were the case.

Then I saw a PCH reading that nearly was matching my CPU temperature before, during and after a stress test I was running on my CPU. It was reaching up to 85c (the factory set thermal limit). It continues to hold pace with my CPU temperature within a single degree--(it makes me think that it must be detecting a different sensor close to or within the CPU and assigning it as a PCH reading (my guess).

However, I also see that there is a chipset reading hovering between 58-63c which I'm guessing is actually accurate.

The "PCH TSI0"reading seems to be following nearly an average of what all my CPU temperatures are reading. I understood that PCH
has become more of an Intel architecture term while AMD has been using chipset. I've seen conflicting information on how hot the PCH
portion of the motherboard can get. (Ive seen 80-110c) as recommended max temperatures.

I would really love to move on and stop worrying about it if it isn't a problem. Does anyone have any insight?
 
Please attach a screenshot of the values in question, I need to see also their exact location.
 
"PCH TSI0" doesn't reflect the chipset here. The dedicated Chipset sensor (Chipset 1 xHCI) is the valid temperature.
