A lot, even. However, if I run sysctl -n hw.acpi.thermal.tz0.temperature in a loop separated by sleep 10, while running a "du /" the results seem fairly predictable: 48.5C 48.5C 48.5C 49.5C 48.5C 49.5C 49.5C 49.5C 50.5C 50.5C 50.5C 51.5C 50.5C 51.5C 50.5C Other than the critical temperature threshold, is it possible to retrieve other thresholds from the kernel/ACPI?
