DampedOrb :
I'm thinking of applying new thermal paste to my 1080 Fe but in case the new one I've got isnt as good where would I be able to get the stock thermal paste or similar in colour at least?
Why would you possibly care what colour it is?
As said above, there typically isn't a huge difference from one paste to another. I have no idea what paste you have, but you can almost certainly get some relatively cheap aftermarket paste that's as good or better than the stock paste.
