You need 99% Isopropyl Alcohol to clean the existing thermal paste before applying a new 1, you can get it from any pharmacy. I strongly suggest not to use grizzly kryonaut, that thing is liquid metal, if you are inexperience in applying thermal paste, the chances of short-circuiting the board is very high, In the future if you are looking to clean your PS4 again it's going to be a big hassle not to mention the advantage it offer is not that significant. Strongly recommend to use Arctic MX-4 thermal paste. Excellent conductivity and easy the apply.
