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, There is no airflow direct at the VRM
Up-close of the front of the VRM.
Up-close of the back of the VRM.
The ROG ZENITH EXTREME stock almost-worst-case thermal testing scenario reveals that the heat sink with integrated heat pipe and fan mechanism is doing its job and keeping things quite cool. In this scenario where there is also no air flow from outside sources, the fan makes a bigger difference. So far, this motherboard is one of the best we have tested.
The results might differ with active airflow, and of course will be better. The fan with early BIOS versions would spin up really loud, later BIOS versions fixed this, and now sync it to VRM temperature rather than CPU temperature (you can manually set it as well).
