I don't know, but if the temperature exceeds 70-80 °C, then you need to start thinking about cooling, or look for the reason for such a temperature, usually the chipset is not very hot, and there is enough passive cooling that comes with the motherboard, the nvme ssd m2 will rather overheat than the chipset))
That is a peculiar question that rarely someone asks.
What temps are you getting on the Chipset? They don't have much variation even if your CPU/GPU temps are blazing hot. My B450 was always at 45-50ºC and the X670E won't even get near 60ºC in any circumstance.
This is a reading from the last 30min, there is not much variation.
If you are having unusual high chipset temperatures I would consider opening a support ticket with your vendor.
If warranty is out, try checking manually if the heatsink is loose in some way, if thermal pads are making poor contact could explain the high temperatures.
