However, combined with the fact that this thing is often too hot to touch with bare skin, I am temped to believe in dK. It is definately too hot. Hence, my desire for the ability to keep the fan on all the time. :-) Last night it was: hw.acpi.thermal.tz0.temperature: 3352 (62.05C 143.69F) Current values: hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 30 hw.acpi.thermal.tz0.temperature: 3302 (57.05C 134.69F) hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: 3692 hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 3702 hw.acpi.thermal.tz0._ACx: 3692 3692 -1 -1 -1 -1 -1 -1 -1 -1 -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org
