I have seen the white stuff dry out plenty of times. Its sure easy to
spot and feel. If you can't smear it then it must be removed.
If its still good, I would just even out the stuff and reapply
components.

I agree in theory. But in practice, thermal grease is so
cheap compared to what it prevents that it is foolish
economy IMHO.



What dries out (white stuff) is not the thermal conducting material.
It should be reapplied solely for best thermal contact.
And the thinnest,most even layer is most optimal.
