This sounds bad, but if it only crashes when you overclock, maybe you have a bad setting. My overclock isn't all that ambitious...at least not with a 2500K. But I disabled all the power saving and hyperthreading options like C1State, etc. The names may differ depending on your exact mobo. Honestly, I left all the voltages on auto and my temps are very low with my H100 (although I did use Indigo Xtreme TIM). I know this isn't an overclocking forum, but I figured my experience may help.
Run Intel Burn Test on your overclock to see if it fails. You are basically going to have to approach this systematically, changing one thing at a time and testing. I know it sucks...but what else can you do? Just my 2 cents.
