Thermal Sensor doesn't get a reading

Level 7

Hello, I have a coolant temp sensor for my Custom loop which worked fine on my previous Asus Mainboard.

I now have a X670E Creator and I don't get a reading from this sensor. It definitely works though since plugging it into my old system shows a temperature.

Is there another port on the mainboard? Also my Proart has 2 additional Pins next to the Thermal Sensor pins which don't show up anywhere. I'm hesitant to plug it in there as I don't want to short anything.


Thanks in Advance!

Can you state the name of the header you're plugging this into? Perhaps take a screenshot of the UEFI monitor tab whilst the probe is plugged in.

It is these pins marked in this image:


The Monitor Tab just says N/A. No matter what orientation I plug it in.

on the Creator model, it is not a liquid temperature sensor but a simple temp sensor

what does this mean? On my old b450 board it worked. What kind of sensor would I need then to get a reading?

So I plugged the thermal sensor back into my B450 and it works. It has to be a bug with the current X670E Bios!

Hello, @ja-ki .

Could you please provide the current BIOS version and the brand and model of the current "coolant temperature sensor" being used?
Also, is the location where you are currently connected indicated in the user manual, as the user mentioned above?

Thank you.

Due to the ongoing regional holidays, my responses may be slightly delayed.
Thank you in advance for your patience.‌‌‌‌ 🙂
