Hi, and thanks for the quick response! No special fancy "fan control policy". 'fancontrol' isn't up or running. Vanilla kernels 3.11.* and 3.12.* had been working on here without any extra work. -- # sensors acpitz-virtual-0 Adapter: Virtual device temp1: +71.0°C (crit = +256.0°C) temp2: +69.0°C (crit = +110.0°C) temp3: +52.0°C (crit = +105.0°C) temp4: +25.0°C (crit = +110.0°C) temp5: +58.0°C (crit = +110.0°C)
coretemp-isa-0000 Adapter: ISA adapter Core 0: +62.0°C (high = +105.0°C, crit = +105.0°C) Core 1: +60.0°C (high = +105.0°C, crit = +105.0°C) -- My notebook (HP/Compaq 6730b) does not have a seperate fan sensor. This is with 3.12.13 with my normal workload.
Please, trust my above mentionned values of 94 °C vs. 74°C as I don't like to boot 3.13.6 anymore, to avoid harm to the notebook's casing.
But I'd do to test any improvement-patch.
