Greetings,
I'm not disputing the existence of these sensors... but where are you getting this info from? Are you just assuming they exist based on what Aida shows?
Contact Aida and ask them wheat the Aux listing is monitoring?
The PCIe is likely the GPU or slot
This is an interesting board due to the location of the m.2 connector
Do you have your CPU fan speed cranked down? Or are you cooling with water? 662 seems low. Airflow through the case is important.
