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).

Controlled airflow 4.4GHz 2.1V VCCIN OCed VRM Thermal Imaging:
Temperature readings are taken at loop 25 of 30 loops of Intel Burn Test with AVX; there is a fan situated right above the VRM heat sink, so airflow is controlled. These are the best results I have seen thus far on any X299 motherboard, and as part of the new generation of VRMs with new heat sinks designed to better cool the VRMs, I am impressed, but I expected this.
Overall, very excellent temperature results, and with the temperature on the back matching that on the front, the heat sink is doing its job correctly.
