It could be due to manufacturing defects or surface imperfections that show up as faint lines.

I purchased the 11900KF some time back and when I opened it yesterday, I saw faint square-like markings on the CPU cover. They look like simple squares but are quite subtle. It seems the unit might not be brand new or could have been left behind during testing in the factory. This makes me a bit cautious. Here’s a picture (for another CPU, just an illustration with light lines drawn; the real ones are faint and thinner due to paint limitations): (Yes, thank you for pointing out the 12700/12900 options—I won’t upgrade to the 12th gen since it would need a different board, a Z690 for voltage control starting around 200-220, and even then I’d prefer a 280 or better. My high-end Z590 was on sale for 89, and the H110 isn’t compatible with the 1700 socket, which would significantly increase costs).
I attempted to create an image using the phone, but it proved extremely difficult to make it clearly visible without assistance. The result resembles the original closely, though the lines appear slightly thinner. This might suggest prior use or testing.
It was likely subjected to a stress test during quality control and assurance processes, meaning it had already been tested under pressure before.
Which option is more probable—used or new orso tested, or a fully sealed box?
If the seal is authentic on its own, then there are just two possibilities: 1. It’s a brand new component 2. It’s a product that has been inspected or refurbished in a factory. Either way, you shouldn’t encounter any issues.
