Power Consumption and Thermals
To measure power consumption we use a killawatt meter and measure the total system power draw at the wall. We run three different use-case scenarios for 5 minutes and take the average reading.
To measure the thermal properties of each motherboard we take the temperature of three different locations using a Rosewill infrared thermometer. We measure the hottest point on the PCH (chipset) heatsink, the first VRM heatsink (which is closest to the rear I/O) and the second VRM heatsink (which is closest to the RAM lanes). The graphs are sorted by the first VRM Heatsink temperature as this is normally where most of the CPU VRM phases reside.
