Today my co-worker set out to DeLid his 4770k. We took the tops off a few old 775 and AM2 chips for practice, using a razor it went pretty good! However the 4770k the IHS didn't have much of a gap to get the blade in so he decided to pound it off. Gave some practice on an old Celeron there, as you can see failed miserably and even made a gouge in the IHS. However he wasn't about to give up so he grabbed his chip and set it up, took a few hits and a few stops due to concern but alas it came off. The thermal paste they used here feels like rubber and it's terrible at it's job! His IHS is really flat so it will probably not get lapped. After new thermal paste and re-assembly the temps 1.25v 4.2ghz went down by 16c full load after an hour+. I know this is probably very high voltage for the clock but we were looking for a base line and haven't really played around with clocking this chip yet.
