Well a cpu diode is a tiny temperature sensitive resistor that on modern amd xps sits on the core, but not in a heat generating part. This is different from the socket temp (sometimes a little blue capped thermistor under the cpu) or the case temp.

Im also trying to work out why your cpu socket reading is so much lower than your motherboard temp.  Are you using asus probe for monitoring? Its got a bug where sometimes it swaps the readings around, see the asus support forum for fixes, I just dont use it. Use either your bios temp reading or try say, MBM5 instead.
