After frying a CPU...

Still, I am not sure what happened. I reseated the heatsink after doing the pencil trick and I'm 99% sure I put it back on properly. It was my understanding that if you bridge the L1 dots incorrectly (which I don't think I did that, either), the cpu could never overheat to the point of destruction, was I mistaken? Thing is I just ordered a new CPU and I don't want to fry this one again, so what can I check to make sure everything is in it's place? The new one will not be unlocked because I vow never to attempt to OC ever again.
 
One of the little problems that comes to the surface a lot is getting the heatsink on backwards. Wouldn't hurt to look at Figures 7, 13 and 14 of this PDF file for a visual example of what to watch out for. Better luck with your new CPU. 🙂
 
Also just so you know, when you connect L1's that doesn't keep the CPU from overheating, what it does is unlock the multiplier so you can change it in BIOS.

Did you make sure to use AS3? Did you use a thermal pad the first time around?
 
Are you sure it's your cpu that fried? Any smoke? If you connect the L1 bridges laterally i think it fries your ram. Better check what went wrong so you don't end up frying your whole system up. Only way the CPU could have fried is if you incorectly installed the hsf or forgot to plug in your fan!
 
Metalloid: sorry for not wording that properly. what i meant to say was, if i unlock the chip incorrectly is there a danger that the CPU could have been destroyed?

I never had a thermal pad. I bought AS3, and applied it and ran the system for about 4 days before deciding to take it apart again. when i was looking at the die i noticed the layer looked a little thin, but thought nothing of it because i know it just can't simply evaporate... that's just what it looks like when it burns in (i thought). i still don't think that's the reason, because if there wasn't enough grease it would not have burned up so fast, i figure it could have at least started to boot windows. i must have not seated the heatsink properly, that's all.

the sticker label on the underside of the cpu is black, the die smells like burned plastic, and it leaked orange stuff out of the south edge of it (and also onto the heatsink bottom). i don't even think i'll try to test it out.
 
If your shim is too thick, it will prevent the CPU from making contact with the heatsink. I wouldn't recommend them... the usual reasoning is "oh, it'll help me avoid cracking the CPU core" but if you install the heatsink in the correct direction, and put pressure only on the end of the heatsink clip when installing the heatsink, you're not going to crack the core anyway.
