unidentified GA-P35-DS3L temperature sensor

[papaschtroumpf]

I have an GA-P35-DS3L and I have identified most of the temps reported by SpeedFan (some of what threw me off is that speedfan mislabeled some ofhte sensors built in my NVIDIA card as being additional CPU temps).

there is still one temp that I can't identify, it's the one I labelled with the question mark in speedfan, see picture:

From the speedfan config file, that temperature is read on:
xxx Temp 2 from IT8718F@$290(onISA@$290)


That temp goes high quite fast when I run Ortho.
I tried to compare those reading s to Everest, and that reading is exactly 15 degrees higher than what Everest calls "CPU". Note that Everest also properly identifies the individual cores, and the "CPU" temp is lower than the cores by anout 7 C, so I'm not sure exactly what it is measuring.

According to the Speedfan "Advanced" settings, the Temp2 sensor is a diode with an offset of 15 degrees (not something I did, I only added the offset of 15 degrees for the Core temps).

Could this sensor be the northbridge temperature? if so, which temp is real, the low one or the one +15 degrees?

OK, so when I reboot and look at the "PC HEalth" in the BIOS, that mystery temp is the one that the BIOS reports as "CPU temp" (it matches the one without the 15 C offset reported by Everest).
I'm guessing the mobo has its own sensor under the CPU socket and that's what it's displaying, it's lower than the core temp because the core temps are measure inside the chip. does that make sense?
If that's the case then I don't need to display this temp in speedfan since the core temps are a better measure.

I'm guessing the temp I labelled as "MB" is the northbridge, it is what the BIOS reports as "system temp". Either htat or it is truly a sensor placed somewhere on the mobo?
when I run ortho that temp doesn't move, should ortho cause hte northbridge to heat up or is it only the CPU?

"Temp 2" is "CPU temp" or "case temperature" (has nothing to do with PC case). It is measured at the geometric center on the topside of the processor integrated heat spreader and its max safe value is referred to as "Thermal Specification" in Intel Processor Spec Finder:

"CPU temp" should not exceed "Thermal Specification". For more details, read
