pmsl you can blatantly see that has far to much heat sink paste on the processor just by looking at it.

I regularly over volt and overclock processors, I've done 100% overclocks in the past and have never ever had a processor die from over heating.

EMT64 Athlons have a maximum operating temperature of at least 65°C with most having maximum operating temperatures which exceed that.

I would bet mobo death as that heat sink is a OEM POS and as such I would expect came of a similar mobo
