We’ve had a handful of these come through. The warranty extension applies even to Tray/OEM CPUs so you might get some traction with Intel of the OEM is annoying about it.
Funny enough, even before this fiasco we had a year where we diagnosed a disproportionate number of Intel CPU failures on 10th and 11th gen systems. 4 or 5 RMAs when 80% of the gaming PCs we saw were AMD, and then there were only 1 or 2 AMD RMAs that year.
