Running: % sensors -v sensors version 3.3.1 with libsensors version 3.3.1 on Ubuntu 12.04 on an Acer Aspire 8930G laptop with: % cat /proc/cpuinfo | fgrep name model name : Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz model name : Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz and I see: % sensors acpitz-virtual-0 Adapter: Virtual device temp1: +38.0°C (crit = +106.0°C) temp2: +48.0°C (crit = +106.0°C) temp3: +48.0°C (crit = +106.0°C) temp4: +43.0°C (crit = +106.0°C) nouveau-pci-0100 Adapter: PCI adapter temp1: +49.0°C (high = +100.0°C, crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +33.0°C (high = +105.0°C, crit = +105.0°C) Core 1: +33.0°C (high = +105.0°C, crit = +105.0°C) The values reported by coretemp are always 33000 millidegrees: % sudo cat /sys/devices/platform/coretemp.0/temp2_input 33000 as observed over the course of a week. I have not tried to intentionally stress the CPU, but had assumed that if it was reading real values, I would have seen some variation. However, I read in the FAQ: http://lm-sensors.org/wiki/FAQ/Chapter3#coretempreturnsunrealisticvalues It isn't really returning degrees Celsius. At high temperatures, the (small) thermal margin is almost expressed in degrees Celsius, but at low temperature, the (high) thermal margin is no longer expressed in actual degrees Celsius. So, if the temperature value reported by coretemp is unrealistically low, all it means is that you are far away from the critical limit so your systems are running totally fine and cool... So does that mean it is expected to see a constant (to 5 decimal places) value, until the cores heat up beyond some threshold? (If so, I'll add this to the FAQ.) -Tom _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
