MSI X399 GAMING PRO CARBON AC TR4 Motherboard Review

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

The X399 GAMING PRO CARBON AC stock almost-worst-case thermal testing scenario doesn't have a mechanism for airflow around the VRM area, so it basically tests the ability of the heat sink to sink the heat.

 

That means that this test is just one way to testing VRM thermal performance, and inside a case, the motherboard would do much better.

 

For a test bench, MSI has included a fan mount that is capable of cooling the VRM heat sink, so they provide the right hardware for scenarios like the one above.
