Been reading up on cpu/heatsink cleaning.
There is a bewildering amount of advice on how thermal paste should be applied.
How do you apply thermal paste. :

The way I do it - a small blob in the middle of the cpu, press down with the heatsink evenly.
The way I learned was to put absolutely the minimal amount of thermal paste. Put a small pea sized amount on CPU, then take a business card and smooth it out as thin as possible.
The goal is to have a paper thin layer. The paste is only for filling "gaps" and manufacturing imperfections when mating the heat sink. ( Too much thermal paste can actually have a negative affect. )
Link to a good guide->

(If you get into industrial applications on SCR's, transistors and power dissipating components then there are precise ways per manufacturer.)
Thanks for all your help.
Last night I completely stripped down a Lenova desktop for cleaning.
Re-assembled the cpu/heatsink using Arctic silver thermal paste using the pea method.
Psensor is reading cpu temp about 30 deg C.
All is well.
Will mark this thread as solved.
