ASUS PRIME X299-DELUXE 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, fans above the VRM that cool the CPU cooler's (Corsair H110i) radiator are turned on to high (12v).

The VRM temperature raised one degree from idle to load, and the front temperature was exact the same as the back when it came to the hottest point. At stock, this is one of the best VRMs I have seen thus far for the X299 platform; it offers excellent light-load and full-load performance.

The heat sink here is working okay; temperature on the back is about a degree warmer than on the front, so it is not too bad. These temperatures are some of the best we have seen thus far, the only better was on a motherboard with a secondary heat sink and heat pipe, so it had more cooling capacity.
