ASRock Z170 Extreme4 / Extreme4+ (Intel Z170) Motherboard Review (Page 10)

Thermal Imaging and Power Consumption

System power usage is measured at the AC/DC PSU (the Corsair AX1200i) which I have connected to another system to measure the test system and as a backup I have a wall meter to verify. The CPU power is measured through the 8-pin connector which is hooked up to a hall effect IC which measures current and puts out a voltage in proportion to the current. That voltage is logged by a National Instruments ADC which logs the DC voltage level, which I then convert into current.

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 really 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 that 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 (H110i GT) radiator are turned on to high (12v).

For the price of the Z170 Extreme4/Extreme4+, you can't expect the best voltage regulator, and even though the temperatures might look high, they are still under the "great" range. The PWMs that run the VCCIO and VCCSA both have integrated drivers and that is why they look like hot spots, their temperatures don't increase with increased current. The VRM for the CPU is decent, it will get the job done, but I do recommend that you use active airflow over the VRM.

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