Temperature 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 connect 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 PCB and the chokes. 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.
Here the board is idle on the left and full CPU/Memory load on the right (Intel Burn Test), you will notice that the hottest part of the board is the Samsung M.2 drive, not the VRM.
The VRM on this board is a little beast. The hottest it got was 36C at the chokes and the same temperature at the back of the PCB. It looks like the PCB absorbed the majority of the heat, and the heat sink isn't really required or effective. This points to a high quality VRM as the parts as specified in their datasheets are overkill for the Z97 platform. I like to see even heat distribution on the top and bottom of the board and all phases look evenly loaded. You should keep in mind that Haswell parts don't eat that much power so the VRMs do tend to run on the cooler side.
The Samsung M.2 drive is the hotspot on the left; it tends to run hot on all systems so nothing to worry about there. The image on the right is of the PEX8605 chip and its voltage regulator which also tend to get a bit warm.
