UPDATE 17/02: Looks like latest driver update addressed this issue and CPU Package shows temperature from correct sensor.
ROG Fan Controller, that comes with Maximus Z690 Extreme motherboard, shows incorrect CPU Package temperature. I found that actually gathered values is belongs to motherboard temperature sensors, not CPU Package. So, looks like sensor isn't named correctly or values gathered from wrong sensor. Moreover, why Fan Controller is lack of sensors variety? It connected directly via USB to motherboard and I have no clue why all other sensors is not included in the list. It makes this controller rather useless compared to contenders paired with FanXpert.
