I got a couple of refurbished Xeon E5-2670 and they came with a blue plastic ring glued onto them, that looks like this:
I have done a couple of builds before and never seen anything like this. It is glued very securely all around the chip. What is this? What is its purpose? The vendor says to rip it off, but I'm hesitant to apply so much force to the chip. Any information would be greatly appreciated.
