This is still BUG 71711 https://bugzilla.kernel.org/show_bug.cgi?id=71711
3.12.15 works very well 3.13.7 fails 3.14.0-rc8 fails
I've tried the tmon tool, now, too. Nice eyecandy and for monitoring!
I've tried to revert all "thermal" related patches from 3.12.14->3.13.7 from 3.13.7. But they don't seem to matter. (Even if I apply the vice-versa patch to 3.12.15.)
So "thermal" is out?
For the failing kernels: Not any reached trip point (active) triggers ONE fan action!
Next would be ACPI, to be investigated,
THX for this audience, Manuel Krause
