I initially thought the case temperature sensor was measuring the switch module's case temperature, which is connected to the cold plate. However, it seems it actually measures the control board temperature. Is that correct?

moniruzzaman,
Yes, there is also a temperature sensor in each power module measuring the case temperature as you described.
Wolfspeed's Thermal Characterization Methods and Applications Application Note describes the location of the temperature sensor in the XM3 power module:
The temperatures can be read in the user interface:
