The pictures below are a better explanation than I can provide.  One model seems to show a very thin pad over the CPU die and the other model has paste over the larger CPU die and a no pad over the smaller one.  You would need to see what contact was being when the fan was screwed into place.  Both dies need to contact the fan through paste or pads and thinner is better

What do you mean conflicting stories ? this post is about how to apply thermal paste, and another post is about how to control fans rpm. two different topics, two different posts. why do you combine them and say it is bump.

You stated you purchased a new fan.

You state:

I bought a new fan for my thikpad x240. The new fan has a cover like on the picture

 

If you did thermal pad removal, install paste on NEW fan, that makes sense . 

Your other post stated you cleaned the fan.  Weird for a new fan.

I read your other post. I understand better now. Your new fan is noisy and you want RPM adjustment like on win 7, via software.  Confusion solved.
