If the reading of that voltage is accurate, the cpu could be fried soon. Has the system experienced any instabilities? Please quickly check the BIOS, reset it to default, and use other application to check the voltage. Most new motherboards will have some bugs like this to show incorrect readings. CPUID HWMonitor itself may also return wrong readings if it doesn't recognize the newer chip related to system readings and monitoring on the new motherboard with the new chipset.
In any case, before confirming the true and accurate reading of the voltage, do not run any burning/testing software to stress the cpu.
