[ SOLVED ] SUPERMICRO X8DTN+-F unknown sensor.

Hello guys,

I need help identifing an unknown sensor om my SUPERMICRO X8DTN+-F. It is 'teml1'. A thermal diode sensor that shows 90C degrees. When I boot the system it shows usually 88C and during working, it grows to 95C. My fans are working overtime  ( i don`t know if it related ) inspite my CPUs are relatively cold. Cpu cooler`s work range is 1500rpm to 2500rpm and they are always at max.

I am gaming on qemu windows 10 VM with the gtx1060. During gaming, the CPU temp stays low arround 42C-45C. It never reaches 50C.

I have pasted the 'ipmitool sensor' info with all the sensors, but nothing is 90C.

Maybe I am missing something? If you have same mother board, can you paste your sensor information?

Any input will be appriciated.

System:
Motherboard: SUPERMICRO X8DTN+-F ( https://www.supermicro.com/products/mot … X8DTN_.cfm )
Cpu: 2 x Xeon x5650
Cpu coolers: 2 x ARCTIC Freezer 7 Pro Rev 2 ( https://www.amazon.de/ARCTIC-Freezer-Pr … B002G392ZI )
Video 1: nvidia gtx 1060
Video 2: nvidia gt  430
Ram: 8x8GB ( 4x8GB per cpu )
BIOS is configured to PowerSave.

I have found and named most of the sesnsors. You can check the info bellow.

Here is what 'sensors' shows:

Re: [ SOLVED ] SUPERMICRO X8DTN+-F unknown sensor.

Hello,

It turns out that it was the north bridge sensor. I have a .... "custom" fan there and it was not working as it was supposed to work. I cranked it up a bit, and now it stays around 65C.

The CPU fans also went down as they are supposed to be.

Thank you.
