Question an unknown motherboard sensor? AsRock x670e PG lightning.

[pangeng]

Dear Community members.

I just purchased x670e pg lightning. I realize this MOBO has two temperature sensors, labeled sensor#1 and sensor#2.
I believe sensor#2 is CPU temperature by comparing its value between different applications.

I dont know what sensor#1 is detecting. It has a weird value which is ~13 degree celsius, meanwhile my room temperature is ~28 degree and CPU is ~60 degree celsius.
I wonder if this is a faulty MOBO, if so I need to arrange a replacement ASAP.

Any suggestion is appreciated.

How did you read the temperature sensors?
Try the asrock software Blazing OC Tuner

update the BIOS, maybe just a bug

what temperature is the BIOS showing?

normal for this board I guess, found similar temperatures on a review (using aida64):

Faulty sensor isn't reason to replace the MoBo.

Also, are you sure that the sensor is showing temps in increasing manner and not in decreasing manner?
By that i mean that temp sensor can show degrees Celsius to Tjmax, e.g 13C left until max temp is reached. Rather than 13C from 0C.

AMD has used this "reverse" temperature scale with their CPUs quite often, whereby one can see CPU sitting at ~25C, while in reality, there is 25C left until CPU reaches it's max temperature (usually 100C). So, with AMD, actual CPU temp would be 75C if calculating the temp from 0C.

Before I used iCUE. Just now I download HWINFO64 and confirmed that this sensor#1 value is from a sensor called Auxiliary. Based on HWINFO64 there are other sensors named AUXTIN1,2,3....which all have abnormal temperatures. I googled those sensors. Maybe, I mean Maybe, they are from unassigned inputs and the temperature value are meaningless.

most likely yes, the board is definitely not faulty
