Well, I don't use lm_sensors for a start! Use the ipmitool utility to probe the readings from BMC cards (ILO, DRAC, they're the same thing). I don;t trust the absolute calibration of the sensors - generally you're looking at setting a limit on which to alarm or shutdown so just take a reading under no load on the CPU and call that the 'normal' reading. I may be wrong. YMMV.
