Many knew something smelled.
This has been on the radar for 2 years, that's why Intel is forced to admit it. It's the sole reason I waited for the D. I'm not sure if the exact problem was known but, while in pursuit to replace a home NAS with a mini-itx, I've read many discussions claiming there was no other possibility for failure rates other than a faulty CPU.
Supermicro and undoubtedly AsrockRack C2000 boards both have atypical failure rates. In the case of Asrock, I believe the failure rate after 18 months is between 60% and 70% (I'm not exaggerating) due to the thermal conditions of all things considered.
