Is this the one you're talking about? root@bigbang [2:38pm][/home/vince] >> sysctl -a hw.acpi.thermal hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.tz0.temperature: 3407 hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: -1 hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 3672 hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 I thought there was a utility that displayed it in Celsius or something.
