What voltages do vcore1 and vcore2 represent? I'm assuming VCore1 is the voltage of the processor, but VCore2 can't be the voltage of a second processor cause I only have one, unless its the voltage of the gpu. I've googled this for a while, but theres no mention of what voltages these numbers actually represent.

Also is there any way, with or without lm_sensors, to get the voltage coming in from the power supply?
