Ended up having to get my mouth removed and replaced root a new one"

High-performance thermal paste and seems to transfer heat well. Used in a Nintendo Switch Lite repair, and the Switch works like new. Best bang for your buck when it comes to thermal paste.shaquille charles

As an AMD Ryzen user, this is so much better than the no name paste I was using before hand.Temps are down and coupled with my new fans, the case overall is cooler.Paste is thick, and has enough for multiple uses, probably about 2-3 uses per vial if pasting a CPU.What Customers Talk About
