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 to the right of the motherboard from the (Corsair H110i) radiator are left on automatic mode (ramps with internal block temperature). Additionally, a 120mm fan is situated right above the VRM, and it blows down at a medium rate (very quiet). Thermal Images are taken at loop 15 of Intel Burn Test
Up-close of the front of the VRM.
Up-close of the back of the VRM.
Thermal Testing at 4.9GHz/1.3v Overclocked Speeds:
The image on the left is always at idle, and the image on the right is at load. During ALL TESTS, fans to the right of the motherboard from the (Corsair H110i) radiator are left on automatic mode (ramps with internal block temperature). Additionally, a 120mm fan is situated right above the VRM, and it blows down at a medium rate (very quiet). We standardize this test with a 4.9GHz on all cores with 1.3V real under load and take pictures at the 80% mark of HandBrake rendering a 4K video.

The Z370 AORUS Gaming 7's thermal performance is excellent, and that's partially due to the new power stages and high-quality inductors. Each of the smart power stages has internal current and temperature monitoring, and the new PWM works with each phase to balance load and turn on just enough phases to get the job done.
Under our controlled testing environment, the motherboard has one of the cooler running VRMs. The motherboard also has a small fan under the IO shield, but it only turns on when the VRMs hit 90C, which didn't happen during our testing.
Anything under 60C is great, 60-80C is acceptable, and anything above 80C is a bit worrisome (if at stock).
