but this is likely bogus.
It will take some time (undetermined, but not zero time) for the thermal diode that we CAN read to heat up to as hot as it would be if the other thermal diode really was at 135 degrees C.
In other words, your idea doesnt take into account the equilibrum of the system, and is thus giving a "worst case" of the difference in temperatures between the two diodes.
On approach would be to use a cooling system that is BARELY inadequate, such that the temperature slowly CREEPS upward.
