In your first screenshot, what's the second temp shown? pmic?

Yes. The first temperature is that of the SoC, the second is that of the PMIC.

Code:

watch -n 1 "vcgencmd measure_temp; vcgencmd measure_temp pmic; vcgencmd measure_clock arm; vcgencmd measure_volts core"
Maybe it would also be important that I use thermal pads from Thermal Grizzly (1.5mm and 1mm for 120x20, 10€ each). In addition, the thermal pad for the SoC, for example, is also 1mm instead of the standard 1.5mm (everything is precisely measured) for better heat transfer:

This is my /boot/firmware/config.txt at the end:

Code:

# Reduce minimal CPU clock from 1.5GHz to 1.3GHzarm_freq_min=1300# Reduce the load CPU voltage by 0.089Vover_voltage_delta=-89000
