Dell M6700 - ACPI temperature sensor location?

Hi,
I own Dell M6700, just upgraded it with GTX980m. After upgrade I'm monitoring temps all the time and I noticed in SpeedFan that "Temp1" is quite high comparing to other ones. This comes from ACPI directly and I wonder where this sensor is located? GPU, both SSD and HDD and all cores are listed here with much lower temps. Air blown by fans is cool.
Fans are still spinning even when all other temps are under 40 degrees.

 

Try running HWinfo or Aida64, it might show some more meaningful names for the sensors.

At least on my M4800, the hottest temp in Aida64 seems to be the PCH around 60C. I'm willing to bet that may well be your case as well.

 

I'll try that tomorrow as it's 1AM in Poland. At least for now I was not able to find any corelation - when I allowed *it* to cool down to 50 degrees and played Crysis on max detail it stayed at 50. But PCH seems to be a good bet - I was copying data over LAN for 4 hours before I noticed this.

 

Wow, this could be a fail of the year. Aida64 showed this as PCH temp. After I disassembled notebook, I noticed that PCH thermal pad was missing. After applying a new one temperatures dropped.

 

Updating this thread as recently I had two other M6700 and both were missing thermal pad there... no signs that it was ever installed. Is that normal on M6700? CPU heatsink has easily visible place for thermal pad over PCH.

 

You're talking about the sizeable chip that is up and to the left from the CPU socket, to the right of the CPU fan? My M6700 definitely came with a thermal pad covering that, and the CPU heatsink has a little "block" clearly meant to accept it.

 

Yup, exactly this. I had three M6700 disassembled and all three were missing it - that's why I'm asking.
However it's located in a way that pad can be easily lost during disassembly/cleaning.
