BIOSTAR Z270GT6 Motherboard Review (Page 10)

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 GT) radiator are turned on to high (12v).

The Z270GT6 has a very basic VRM, the most basic I would go with if you plan on any overclocking. Its performance isn't in the danger zone or even the bad zone, it's just average, and BIOSTAR doesn't claim differently.

The really good news is that the VRMs are being cooled quite well even though half of them don't have a heat sink. We see that the temperatures on the rear of the motherboard were never higher than on the front, indicating the heat is being dealt with where it is produced.

Anything under 60C is great, 60-80C is acceptable, and anything above 80C is a bit worrisome (if at stock).
