It can be made in either China or Malaysia.
There can be small surface scuffs and scratches yes, but not deep gouges.
The box is sealed on top and bottom with a paper sticker, it is (sadly) not shrink wrapped, which allows people to easily scam Amazon. My first Ryzen 1800X box was empty!
Temperature isn't a problem, and moisture isn't as long as it's dry when it's installed, these things go across oceans in uninsulated shipping containers.
I wouldn't be concerned of the where made but the pictures of both those cpus look to have thermal grease buildup on the edges, one worse than the other. Unless you applied it and took, it off for these pictures, I'd say you got a used CPU again.
