VRM temp refers to the temperature of the voltage regulator module (VRM). This is difficult to spot in HWMonitor because the VRM doesn’t always have a temperature sensor built into it – this depends on the decisions of the manufacturer. Thus, HWMonitor doesn’t have a slot in to display format for this temperature and its position can change depending on the motherboard brand being monitored. You have to guess which is the VRM temperature – some users have reported TMPINT2 as this value.
