Hi Guys! Haven't built a PC in a long time but just purchased the i5 8600k! (oem) Yay! But it appears to have a barcode sticker on the back of the actual CPU itself, annoyingly it's not an easy peel so it has obvioulsly got bits left on the CPU itself, is this an accidental sticker-ing? Or should i just remove it with the usual cpu thermal compound remover? Thanks!
