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 back side 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

The Maximus XI Formula has excellent VRM thermal performance. While it's not the best we have seen, that is mostly due to the fact that it's using a waterblock as a VRM heat sink, but regardless, the thermals were acceptable, and temperature rises weren't bad. Anything under 60C is great, 60-80C is acceptable, and anything above 80C is a bit worrisome (if at stock).
