I have this cpu here. Is the topside metal? plate with the printing on identifying the cpu supposed to be removable?? The topside of the one I have here is 1" green mica square with small centre shiny metal square (cpu die?) on 2 outer edges of mica is 2 small black strips (some kind of adhesive?) To explain further this is a cpu that was replaced in my PC (along with Mobo & HDD) sort of why bother to trace a fault just change everything! I'm not convinced this cpu is faulty & wish to retest it in my PC. So do I 'prise off' the metal plate on existing cpu to put on replacement before fitting? if so do I put thermal paste between plate & cpu die? Or can I buy this metal thingy/plate. Hopefully this makes sense to someone, I'm not sure I understand it!
