Ok, so we all know that TMPIN1 is your CPU temp ( at least in most cases ) but the other 2 tend to be a little sketchy. Considering that I've put some sensors around from my Scythe Kaze Master Pro I thought I'd share what I found out.
Either the MB / fan controller sensors are completely out of whack or TMPIN0 and TMPIN2 aren't what I thought they were, at least on GA-790XTA-UD4.
It'd seem that TMPIN0 is actually NB temperature and TMPIN2 is mosfet temperature. One bit of doubt on my side is Scythe reports NB as 26C and mosfets at 35C idle. HW Monitor says both are 30C. At load, though, both sets of sensors are about the same. NB seems to peak at 35C and mosfets at 44C. That's my biggest reason for thinking that TMPIN2 can't be the NB. I've placed the Scythe sensors right on top of the heatsinks and I'm not really willing to believe that there could be a 9C difference between the heatsink top and NB chip ( if the MB sensor is near it ).

What you need to do to confirm it is to spray some coolant vapor onto the heatsink as you are testing the temperature. You will soon see a sudden drop in both dispalys.
