my x100e was just getting too hot. too **bleep** hot. darn thing started shutting off on me fairly regularly.
so i took the entire thing apart. heres what i found:
a) too much factory thermal compound was originall applied. this will decrease cooling performance.
b) most of the thermal compound on my CPU was 'burned' off. i think this is due to the x100e being a hot system to begin with, and lenovo using cheapo thermal compound.
pics (sorry, camera phone):

^ notice the thermal compound all around the edges. quite a bit really.

^ notice all the bare CPU real estate. not good.

after it was cleaned, i used some basic arctic silver 5.
a modest improvement. used to hit 80 (via TP Fan Control) regularly under full load, and would occasionally hit 85 with 100% fan. now, it hits mid 70s under full loud, with the rare 80... but once the 100% fan kicks in, it very quickly drops to mid 70s. these temps are with fresh thermal compound, so the temps should improve a tiny bit over time as well.
no shut downs yet, and the fan is generally less active. all in all a win. my x100e is still a very warm machine, but if it isnt forcing itself to shut down, im happier.
its a small pain to basically do a full disassemble of the x100e, but improvements can be had.
hope this helps anyone.

A couple of things that should help: the Hardware Maintenance Manual, and the training video (hit the "take course" button).

i did it! disassembled whole thing because it is needed to get access to heatsink and cpu and this is what i found:
crap on down side of heatsink:
closeup on crap on cpu:
after i cleaned it up i put a little bit of my own thermal paste and screwed all thing back.
and i tested it playing 3D game for 20 minutes, here are results:
so obviously this helped. looks like that fabric thermal paste that they put in lenovo factory is bad, and also i think they put too much of it. so after few years under high x100e heat paste change its structure into something clay like and starts to suffocate poor processor and unable to get rid of that heat his end is inevitable.
i followed disassembly steps that zoltan provided:
but they omitted few things like they didn't mention i have to disconnect wlan cables and during systemboard disassembly they omitted didn't mention i have to disconnect one connector. and this is dangerous because if you are disconnecting part without disconnecting all cables and connectors first you can make damage. so before you remove any part inspect from all sides if there is anything still attached.
thank you guys im off.
