Thermal paste

[sargan]

Just on start of new build …
Watched a ‘Build your own PC’

Advice is connect up all components and check all powers up before assembly in the case.
Fine and valid advice.
The videos show applying Thermal paste, and fitting AIOC pump head … fine.
However when I dismantle this, do I need to clean off Thermal paste, and re-do.
Or just add a bit more fresh paste on top of what is there, or just re-use it as is and not add anymore or any new

Previously I built in the case .. just watched 2 videos on 'build your pc' and both were advising build it outside of the case, it seemed logical ..... maybe I won't bother.

Yes I appreciate its to validate the components.

The videos advise build up first to check out components, and if need be to make fault finding easier.
I have only built 3 pc's and they were built in the case.
