and exactly how many times did your cpu`s die because of a factory fault after 1 year? (died because of other things doesn`t mean you have warranty)
my 2 cents: if you have a decent cooler or want to buy a 3th party cooler, get the oem. it`s cheaper and one year is enough, after that they don`t die within 10 years except when you overclock (maybe) or get a psu fault (maybe) but then you have no warranty with the retail either.
