(Get the code!)
May be, in the past that was something that helped me, you should check your startup-logfiles for messages that indicate problems with the graphic driver. I am not expert, so I can not tell you exactly what I did, but it turned out that Ubuntu used a fall back graphics driver instead of the real one, which caused the system to be slower and also caused the overheating. I can not remember exactly, but in one Ubuntu version I googled the error message and found instructions to fix it. In another version I just learned about the xorg-edgers-ppa with the newest versions of graphic drivers (and also fresh kernels). That helped very much and I am running them ever since (but on my x201 I do not have over heating without xorg-edgers)
You may also check, if your system is using Thinkpad-ACPI instead of ACPI. This should happen automatically. Otherwise you need to enforce it on system startup. Do not ask me exactly where, just google it, that was what I did.
What also helps temporarily: Remove the battery if you work on AC.
