Well, yes, that's a temperature monitoring chip, what else would you want it to be used for? > What have people used in real world examples for this chip? Usually M/B > temp and CPU temp?

Yes, temp1 = M/B temperature and temp2 = CPU temperature is the most typical usage for LM90-like chips on mainboards. On graphics cards, they are used as temp1 = card temperature and temp2 = GPU temperature. > Though the k8 temps measure each core. And...

The K8 internal sensors have not impressed us by their reliability so far. See the note on http://www.lm-sensors.org/wiki/Devices and various reports on this list. The LM90 temp1 reading should be accurate out of the box, no compute statement needed. The LM90 temp2 reading might need an offset, depending on the thermal diode model being used. Ideally, the BIOS would have set it up properly, so that it itself reports accurate temperature readings. I agree that the LM90 temp2 value is quite high on your system, but I would tend to trust it, especially if the BIOS reports the same. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
