Thermal Imaging and Power Consumption
System power is measured at the wall with an AC power meter.
Note on Thermal Images: In the temperature section, we use our Seek thermal imaging camera to capture the surface temperatures of major components on the board. I look at the VRM and then all other things that light up the screen. If there is something to worry about, then I will state it. Otherwise, I will just show the hotter running parts of the board for fun. Unless some component is over 80-90C, then there isn't anything to worry about.
All systems will act differently, so I will look for commonalities, such as how far from the VRM the heat spreads through the PCB and the difference in temperature between the front side and backside of the PCB. Keep in mind, the majority of the heat from the VRM goes into the PCB as it is a giant soldered on copper heat sink. A larger difference in temperature between the back and front of the PCB points towards a more effective heat sink.
Thermal Testing at Stock Speeds:
The image on the left is always at idle, and the image on the right is at load. During ALL TESTS, fans above the VRM that cool the CPU cooler's (Corsair H110i) radiator are turned on to high (12v).

Up-close of the back of the VRM.
Overall VRM thermal performance is excellent, but remember these are results at stock settings, not a 4.7GHz 9980XE. We see solid thermal distribution, and the active fan and heat sinks do seem to help cool the VRM and PCB. We see a 2C increase on the front and a 4C increase on the rear of the PCB. Overall excellent, but do keep air flow over the VRM area in your mind if heavily overclocking the 9980XE.
