No special fancy "fan control policy". 'fancontrol' isn't up or=20 running. Vanilla kernels 3.11.* and 3.12.* had been working on here=20 without any extra work. -- # sensors acpitz-virtual-0 Adapter: Virtual device temp1: +71.0=B0C (crit =3D +256.0=B0C) temp2: +69.0=B0C (crit =3D +110.0=B0C) temp3: +52.0=B0C (crit =3D +105.0=B0C) temp4: +25.0=B0C (crit =3D +110.0=B0C) temp5: +58.0=B0C (crit =3D +110.0=B0C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +62.0=B0C (high =3D +105.0=B0C, crit =3D +105.0=B0C) Core 1: +60.0=B0C (high =3D +105.0=B0C, crit =3D +105.0=B0C) -- 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 =B0C vs. 74=B0C as I=20 don't like to boot 3.13.6 anymore, to avoid harm to the=20 notebook's casing. But I'd do to test any improvement-patch. Manuel Krause
