So you are saying the "Temperature" column here is coming from a circuit on the die, not an LM75 component on the board?
It is not either an LM75 ic
OR a circuit on the die because it is
BOTH of those things. The LM75A (if that's what's installed) is "a temperature-to-digital converter using an on-chip band gap temperature sensor"; all it does is convert "temperature-to-digital" such that it can be presented as illustrated above.
How exactly do you think the LM75 would sense the temperature of the chip if it were not connected to a circuit on the die?
