No, the "test /switches" test on XO-1.75 does not test the temperature
rise of the CPU.
When Q4B10 is released, a thermal sensor watchdog reset will be
enabled, which will reset and then power down the unit if the CPU
temperature exceeds 85C. This will occur in OFW or Linux.
"watch-thermal" will be available to display the thermal conditions.
"test-thermal" will be available to test the mechanism by lowering the
threshold temperature to a few degrees above the current CPU
