If anything can be done, this is through ACPI. Just for reference: I asked at the linux-acpi list and they advised me to add termal.crt=<value> to the kernel boot paramters, which I did (<value>=99) and it actually sets the temperature of the virtual device. Now I get: # acpi -V Thermal 0: ok, 64.0 degrees C Thermal 0: trip point 0 switches to mode critical at temperature 99.0 degrees C Thermal 0: trip point 1 switches to mode passive at temperature 105.0 degrees C and acpitz-virtual-0 Adapter: Virtual device temp1: temp1_input: 66.000 temp1_crit: 99.000 coretemp-isa-0000 Adapter: ISA adapter Physical id 0: temp1_input: 66.000 temp1_max: 86.000 temp1_crit: 100.000 temp1_crit_alarm: 0.000 Core 0: temp2_input: 63.000 temp2_max: 86.000 temp2_crit: 100.000 temp2_crit_alarm: 0.000 Core 1: temp3_input: 66.000 temp3_max: 86.000 temp3_crit: 100.000 temp3_crit_alarm: 0.000 pkg-temp-0-virtual-0 Adapter: Virtual device temp1: temp1_input: 67.000 Thanks for your hints, Thomas _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
