I just had 2 semprons bite the dust. As in nice scorch mark in the center. No oc'ing. But in my case i bought them as a mobo/cpu combo and stuck them in value systems that I resold. I think they heated up and the seperator (yes seperator, had i known i would have taken them out) expanded enough that the core was no longer in contact with the hs/fan. Am I nuts or anyone else come across this or something similar? I got them from newegg so had no problem returning them but its not the most shining endorsement of my business either. Its the m7vig/sempron 2500+ combo. Any thoughts?
