If you have an R360 core on your 9800 Pro/XT, and you have an XT PCB with the LM63 IC on it, then you can use your card's temperature probe.
Some manufacturers, like MSI, use non-reference PCBs for some of their cards, which means that the card may or may not have LM63, regardless of whether the card has an R360 or an R350 core.
Any 9800 with a Pro PCB, and no LM63, either doesn't have, or can't use the temperature probe.
