Oh dear god.
Of course it comes right off, it's thermal paste, not glue. It also doesn't need to stay paste, even if it dries out the stuff that's in there will conduct heat just fine. In my 20 years of building computers for myself and others have I ever heard something that dumb, it's never down to thermal paste, heat transfer almost always boils down to bad case design, not taking advantage of the fans that are there or obstructing air flow, usually from dust that accumulates in fans and/or filters, or massive overclocking. Generally speaking the thermal paste that comes with your cooler is fine, you don't even have to buy the super expensive ones. Yes, there is slightly fancier thermal paste that will have a bit of an advantage but don't tear apart your PC or especially laptop to change it out, it will do nothing and just be a pain in the ass. Clear your dust filters and fans every once in a while though.
