HWiNFO64 had unlabeled sensors, so the reviewer used an external laser temperature gun on the heatsinks. The large primary VRM heatsink surface reached 44 C and the smaller VRM heatsink to the north of the CPU reached 45 C. The highest value, 45 C, is stored. This is a heatsink surface reading, not a VRM sensor. The cooler, the CPU package power, the settings and the ambient temperature are not stated.
