I got some advice from the PC shop.
So I just put a small ammount in the midle of the core, and then just put the heat sink on.
The thermal stuff will spread out under the preasure.
So I did not spread it out with my finger or anything.
So far so good, im typing on the puter now

Waiting for Windows to install all the windows updates

What NOT TO DO is what I did when I installed my first CPU !
Do not put the thermal stuff on any other components but the center core on the CPU.
I figured, that I put the suff on all the small black things (transistors?) on the CPU, and that was no good, PC did not even boot up. So I had to clean it and re-aply
