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.

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.
