The VRM's are under the Heatsink to the left of the CPU socket. And 81*C is VERY hot! I would becareful. And your motherboard is NOT backwards. If you look at your idle and load voltages, under load the voltage decreases (vdroop). You do not want this. You are not using the correct test either.
Click options, torture test, custom -Min FFT 4096, and memory-as much as you have free.
And it can not be too stable if it says the max Voltage for VN VIR was 1656 :lol:
I don't use that program though, I prefer OpenHardwareMonitor personally.
You have to understand the heatsink is taking the heat to cool the component. So it won't read 100% as if you were to target the VRM's directly. Also, if you have something blowing at the VRM's, you're blowing hot air off the heatsinks helping to cool them, but the Heatsinks will be cooler than the VRMs.
