The value reported by hw.acpi.thermal.tz0.temperature most likely comes from a temperature sensor mounted somewhere on the motherboard, while hw.coretemp.delta reports the temperature inside the CPU itself. In my experience, Core-based CPUs run very cool under light load, so the result does not surprise me. here's what coretemp reports on my file server: hw.coretemp.tjmax: 100 hw.coretemp.delta: -46 although I believe this is actually one of the CPUs that have an 85°C Tj(max), giving a core temperature of 39°C and not 54°C (the box has a 2.4 GHz C2D but spends most of its time barely ticking over at 200 MHz) DES -- Dag-Erling Smørgrav - [EMAIL PROTECTED] _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
