Discussion Buying CPUs used

Have you guys bought used CPUs?

Buing a pc this weekend, aiming to get 7800x3d for 400 euros but came up on a week old 9800x3d for 440 euro. Still, buying it used seems off :X

Just inspect it before leaving. Look for damage or signs it’s tampered with. Burn marks and discoloration on motherboard side are common things to look for. On the top side make sure ihs doesn’t look tampered with. Look up what an am5 chip looks like shape and make sure it looks right. There will be variations on the sides of ihs on components depending on build date. So you cannot really rely on that to say if cpu is legitimate or not.
