TMPIN2 (what we think is the socket) tends to idle around 3 to 4 degrees cooler.

The only think that I still can't figure out is that the CPU temperature in the bios idles around 27C, which is withing 1 or 2 degrees of TMPIN1's idle temp. I was thinking about unplugging one of my heatsink fans to see which temperature reading goes up, but if you're correct and TMPIN1 is the CPU-NB then I should see both temperatures rise, which wouldn't help me much in determining which is the CPU socket. But it might let us correlate your HWM temps and know which is which. You would have to post pic of it since it has so dang much info that is really useless when trying to help a newbie that is just confusing and hard to scan all the numbers. HWiNFO/32/64 Tools Website has freeware download. I just thought of one idea that might work. I have seen users speak of blowing freon on the VRMs to see temps drop and know for sure which of those temps and a particular board was the VRM temp and that made the other the CPU/Socket temp. I have seen temp 1 and 2 close together in HWM and that is a pain to know which is which on that dang Giga board, but neither temps was near an issue so it was not a big issue. Have you got a capture of HWMonitor under load? Run P95 Blend for about 30 mins to be sure the temps are fully up as high as likely to go and post while P95 Blend is running caputure and then post the capture so we can look at the temps shown. However, the 'CPU temperature' reading in the bios stays right around 27C idle = Yes it would in bios since it is not reading a loaded temperature.

It makes sense to me that the Northbridge would be running hotter than the CPU, but it does NOT make sense to me that my CPU temp would max out at 42C with a measly CM Hyper 212+.

To sum all of that up, my questions for other GA-970A-UD3 owners are:ġ) Which HWM value is actually the CPU temp? TMPIN1 or TMPIN2?Ģ) If TMPIN1 is the CPU temp then what is TMPIN2? Northbridge? Is it possible that my 212 Plus is keeping my 8 core CPU at only 42C? This seems very low to me considering I only have a Cooler Master Hyper 212 Plus. The only thing keeping me from believing that TMPIN1 is the CPU temp is that TMPIN1 maxes out at only 42C under full load at a 4.5GHz overclock. Furthermore, the TMPIN1 value in HWM idles around 27C, which makes me think that TMPIN1 is actually the CPU temp and NOT TMPIN2 like I had previously thought. However, the 'CPU temperature' reading in the bios stays right around 27C idle, which is a few degrees higher than the TMPIN2 value in HWM. It will go anywhere from 23C to 54C based on CPU load. For the last couple of weeks I've been under the impression that TMPIN2 is the CPU temp because it seems to fluctuate the most based on CPU load. The other two values have me stumped though.

The TMPIN0 reading usually stays at 33C which is what I always see in the bios. It's pretty obvious that TMPIN0 matches the 'System temperature' reading in the bios so this must correspond to some sensor on the motherboard. HW Monitor gives me three temperature values: TMPIN0, TMPIN1, and TMPIN2. I've been scratching my head over the HW Monitor values for the last few weeks trying to figure out what is what. I'm hoping there are some other Gigabyte GA-970A-UD3 owners on here that can help me figure this out.
