# What do all these voltages mean?

Im running a program called lm-sensors on my computer. It monitors the current state of my hardware. Here is an example of the output it gives.......

VCore 1: +1.30 V (min = +1.42 V, max = +1.57 V) ALARM
VCore 2: +1.49 V (min = +2.40 V, max = +2.61 V) ALARM
+3.3V: +6.46 V (min = +3.14 V, max = +3.46 V) ALARM
+5V: +4.92 V (min = +4.76 V, max = +5.24 V)
+12V: +12.03 V (min = +11.39 V, max = +12.61 V)
-12V: -19.87 V (min = -12.63 V, max = -11.41 V) ALARM
-5V: -2.56 V (min = -5.26 V, max = -4.77 V) ALARM
Stdby: +5.00 V (min = +4.76 V, max = +5.24 V)
VBat: +3.18 V
fan1: 2909 RPM (min = 0 RPM, div = 16)
fan2: 0 RPM (min = 332 RPM, div = 16)
fan3: 3308 RPM (min = 664 RPM, div = 8)
M/B Temp: +41°C (low = +15°C, high = +40°C) sensor = thermistor
CPU Temp: +46°C (low = +15°C, high = +45°C) sensor = diode
Temp3: +41°C (low = +15°C, high = +45°C) sensor = thermistor

I just want to know which of the following values/rails apply directly to the CPU itself.
VCore1=1.3
VCore2=1.49
3.3
5
12
-12
-5
stdby =5
Vbat 3.18

And Why is there 2 Vcore's. Is one of them the chipset?

Thanks
