The first is the "system" temperature. (I have no idea exactly where this is measured, but I suspect the northbridge), the second is CPU0 and the third is CPU1. By CPU0, I mean the package, not the core. I typically see a "temperature" way below room temp for CPU1, which I don't have. Since modern CPUs all have internal temperature sensors and they connect to pins on the package. If the chip is not there, the circuit on the mobo that "translates" this analog value tends to drift around with the temperature of its components, but not in an obviously meaningful way. Right now I show a system temp of 30C, a CPU temperature of 34C and a phantom of 15C for the missing CPU. (The room it's in is at about 22C.) The second Vcore is similarly silly. Now, why does my mbmon work out of the box and you need a small patch? -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
