I don't want to hurt this Ad but I need to say that the warranty at Intel is no go for this CPU as when you RMA directly at Intel you need to be the original buyer, it's multi threads at reddit regarding that some kids get issues due to the fact that there mother has bought it for them. But they can still use the warranty as they live in the same house.
But the warranty at the reseller maybe still are valid.
I have done a RMA at Intel and they req proof of purches with your info on it.
