Let's start with my actual GOOD kernel:

# uname -r
3.12.16-ck2
# grep . /sys/class/thermal/thermal_zone*/cdev*/device/path
/sys/class/thermal/thermal_zone1/cdev0/device/path:\_TZ_.FAN4

/sys/class/thermal/cooling_device6/device/path:\_TZ_.FAN4
/sys/class/thermal/cooling_device7/device/path:\_SB_.PCI0.GFX0.DD02

And have a newer BAD kernel:

# uname -r
3.13.8-ck1
# grep . /sys/class/thermal/thermal_zone*/cdev*/device/path
/sys/class/thermal/thermal_zone1/cdev0/device/path:\_TZ_.FAN4

/sys/class/thermal/thermal_zone2/cdev0/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone2/cdev1/device/path:\_PR_.CPU0
/sys/class/thermal/thermal_zone3/cdev0/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone3/cdev1/device/path:\_PR_.CPU0
# grep . /sys/class/thermal/cooling_device*/device/path
/sys/class/thermal/cooling_device0/device/path:\_PR_.CPU0
/sys/class/thermal/cooling_device1/device/path:\_PR_.CPU1
/sys/class/thermal/cooling_device2/device/path:\_TZ_.FAN0
/sys/class/thermal/cooling_device3/device/path:\_TZ_.FAN1

/sys/class/thermal/cooling_device5/device/path:\_TZ_.FAN3
/sys/class/thermal/cooling_device6/device/path:\_TZ_.FAN4
/sys/class/thermal/cooling_device7/device/path:\_SB_.PCI0.GFX0.DD02

The "grep . /sys/class/thermal/cooling_device*/device/path" results stay 
always the same as above, so I omit them in the following.

There are generally only two different re-occurring scenarios for
"grep . /sys/class/thermal/thermal_zone*/cdev*/device/path", so that I 
want to abbreviate them in the following:

Scenario-1:
# grep . /sys/class/thermal/thermal_zone*/cdev*/device/path
/sys/class/thermal/thermal_zone1/cdev0/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone1/cdev1/device/path:\_PR_.CPU0
/sys/class/thermal/thermal_zone1/cdev2/device/path:\_TZ_.FAN0
/sys/class/thermal/thermal_zone1/cdev3/device/path:\_TZ_.FAN1
/sys/class/thermal/thermal_zone1/cdev4/device/path:\_TZ_.FAN2
/sys/class/thermal/thermal_zone1/cdev5/device/path:\_TZ_.FAN3
/sys/class/thermal/thermal_zone1/cdev6/device/path:\_TZ_.FAN4
/sys/class/thermal/thermal_zone2/cdev0/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone2/cdev1/device/path:\_PR_.CPU0
/sys/class/thermal/thermal_zone3/cdev0/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone3/cdev1/device/path:\_PR_.CPU0

Scenario-2:
# grep . /sys/class/thermal/thermal_zone*/cdev*/device/path
/sys/class/thermal/thermal_zone1/cdev0/device/path:\_TZ_.FAN4
/sys/class/thermal/thermal_zone1/cdev1/device/path:\_TZ_.FAN3
/sys/class/thermal/thermal_zone1/cdev2/device/path:\_TZ_.FAN2
/sys/class/thermal/thermal_zone1/cdev3/device/path:\_TZ_.FAN1
/sys/class/thermal/thermal_zone1/cdev4/device/path:\_TZ_.FAN0
/sys/class/thermal/thermal_zone1/cdev5/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone1/cdev6/device/path:\_PR_.CPU0
/sys/class/thermal/thermal_zone2/cdev0/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone2/cdev1/device/path:\_PR_.CPU0
/sys/class/thermal/thermal_zone3/cdev0/device/path:\_PR_.CPU1
/sys/class/thermal/thermal_zone3/cdev1/device/path:\_PR_.CPU0

Already, during bisecting this issue, I've found out, that these scenarios
have something to do with rebooting: So, I've rebooted the new bisected kernel
twice in the second roundup.
But I haven't expected the following disorder:

This is a row of results from last night, rebooting different kernels, one
after the other, and capturing some relevant data.

Please, mind, what doesn't come from this data: 3.13.x _never_ triggers 
a new fan speed when needed (higher/lower). 3.12.x _always_ does, at 
least after hitting a higher active temp trigger!
