Both of these are interesting, "k10temp" is your APU (CPU+GPU)
I don't know what "thinkpad" is supposed to be. Casefans perhaps ? Or a master controller for everything ?
You might also want to try this:
ls -1 /sys/class/hwmon/hwmon5 |grep 'pwm\|fan'
You mean this one ?:
It might work on your laptop if you have a file or directory called /proc/acpi/ibm/fan
You can check this by issuing this command:
cat /proc/acpi/ibm/fan
If such a file or directory exists on your system, you can download the .deb and install it, create the /etc/modprobe.d/thinkpad_acpi.conf as explained in the description (if it isn't enabled yet) and it is supposed to work probably after a reboot.
If it doesn't, look here: [SOLVED] Thinkfan and sensors simple problem / Newbie Corner / Arch Linux Forums
tlp has a lot of tricks to minimize energy consumption and maximize batterylife, the more or less unintended sideeffect is ofcourse: lower temperatures. So I think it is reasonable to expect tlp to help in this regard unless you run heavy loads
