I bought my cpu in September 2018 and intel said my warranty expired September of this year and then acted like they were doing me a favor by giving me a "1 time exception". Its a 3 year warranty. Maybe the tech support person didnt count it right? Is it 3 years from when it was made instead how long you used it? It's not that important and the rma process was mostly painless, but it would good to know for in the future.
