What sensor does the motherboard's CPU temperature relate to? I can't figure out if this is a miss-read or if something on my board is frying. My PC started resetting itself a couple days ago.
That CPU temperature shown is definitively wrong - probably a not connected sensor. I don't have more details about how sensors are connected on your HP mainboard.
Your CPU cores (DTS) report ~30 C with max @ ~50 C which is very well.
