I really want to, but that warranty and price of the cpu is holding on me, If i have some more feedback i'll do it.
1. Your CPU is experiencing something call "Hot-Electron Degradation" because of your core-voltage, regardless of whatever temps you might have. That voltage of >1.5 will ABSOLUTELY
lower the life and performance of the Silicon Oxide gates over time. Your temperatures will not have a huge effect in that regard.
If you're game, then read this paper that will explain it extremely well to you
2. However, if you're looking for an extremely long life out of that CPU, you honestly shouldn't be overclocking. Without giving you a lecture, these chips are made to last >10 years in certain applications if left at stock and cooled relatively well. Lapping will give it a bit more life due to the greater thermal transfer, but unless you know how to properly apply thermal paste in this situation (Microscopic amount), you won't notice a difference whatsoever.
3. My initial reaction to this was "man up and get some cahones." Honestly, I have done it, and it's a difference of 2c at most for the CPU, the heatsink was about 5c. If you do decide to do this, you should NEVER lap with sandpaper finer than 1200 grit. I personally only ever go up to 1000. It's amazing how stupidly people will apply thermal paste at grits of 2000 or 2500. If you sand that finely, you're so close to being flat (that is, assuming your technique was correct) that the advantage of using thermal paste is almost negated.
I'll PM you this just so you get it, but in your case, I WOULD NOT recommend doing that in your case unless you can easily go into a store tomorrow to buy a replacement.
You vcore is already a bit too high for my tastes (and Intel engineers as well) So I would probably lower the OC to 3.6. However, that's simply personal preference. I went down from 3.6 to 3.4 simply because I can go from 1.46 to 1.40 in my vcore. That's an incredible difference for only 200 mhz.
