Ok, wasn't going to post here anymore but i'll bite on this one occasion as you seem to be even more retarded than i originally thought or lack the ability to decipher information that's previously been posted in this thread.
The reason i delidded was constantly hitting 90-95deg running 27.9 with a core voltage of 1.25v. This chip i'd already proven to scale well so with a lot of headroom on voltage and none on temp, the only way to OC higher was to a) delid and b) run a custom water loop.
I don't run my chip at 81deg 24/7, neither is Menphisto. That 81 deg was max temp whilst running an AVX2 application at 100% load for considerable time which is no where near the stress he will exert on the core during normal use.
So yeah, silly me for posting a 'fail' comment from the start.
Keep dishing out the useful advice.
People like you will certainly never learn. Delidding isn't for those who only have an OC headroom in their chips, but rather for the betterment of the overall temps, for 24/7 usage.
Haswell spikes even on as low as 1.200V as the gap in actual temps are still 20-25C, with a delid job. Some are happy with the warranty, lack of risk, while others aren't.
I just find it quite frankly stupid enough for someone not to recommend delidding, when while they've done it themselves, keeping the OC potential crap on one side and just looking at temps as that's the main reason why it's done. Fail as it is....
