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 X399 Designare EX's new redesigned heat sink is built to take full advantage of any case airflow. However, this worst case testing scenario doesn't do it justice, and if the MOS temperature doesn't go over 90C, the VRM fan won't spin up.
The VRM fan didn't spin up, but our VRM stayed within operating parameters. It's the same physical VRM as the X399 AORUS Gaming 7, and the topside heat sink temperature is a few degrees cooler while backside temperature is a bit hotter, and that's due to the Gaming 7 having more mass, while the Designare EX is designed for a case environment with airflow. In a case, the Designare EX should do much better than the Gaming 7. Things stayed under 60C, so I would say it had great thermal performance.
