If it is, do you know where fan level information comes from? You do not seem to have ACPI fan devices defined there: hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.user_override: 0 hw.acpi.thermal.tz0.temperature: 72.5C hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.passive_cooling: 0 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: -1 hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 126.0C ===> hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 hw.acpi.thermal.tz0._TC1: -1 hw.acpi.thermal.tz0._TC2: -1 hw.acpi.thermal.tz0._TSP: -1 If all you want is to make your system cooler during the operation, you could try setting hw.acpi.thermal.tz0.passive_cooling=1 hw.acpi.thermal.user_override=1 hw.acpi.thermal.tz0._PSV=70C either in /etc/sysctl.conf or manually and see whether this makes a difference. -- Alexandre Kovalenko (Олександр Коваленко)
