Need to stop reading this thread, my 3770k keeps taunting me to remove its lid lol 
De-lidded 3770k!!

Exactly what i have done, gotta watch the gc though, find it like treacle, got to treat it like a bottle of wine and twist before you pull away otherwise it goes everywhere!! Good job its non conductive
And the liquid metal really is like liquid metal, it runs!

Sweet got it ordered, should be delivered for Monday. Will get some sand paper aswell so I can give it a lap. Still looking into the direct fix but not read much on it..
you will use wet and dry paper and not sandpaper wont you

VID isn't Vcore, all the 1.52V value is, is the biggest value the VID register can hold. It means nothing more than that. Intel DO NOT give a max recommended Vcore for either SB or IB. They do give one for SB-E - 1.40V I think off the top of my head and they might give one for IB-E but I've not checked. Any reference to max safe Vcore for IB or SB doesn't exist in the datasheets.
@Jokester, what is VID??? seen some others and mine seems high @1.33/stock

Haha yeah ill get some green oxide out the van! Nah got plenty of glass paper/wet and dry in the van but will read a guide quick just to confirm, sure I wouldn't mess up the lapping though.

VID is the voltage the processor requests from the motherboard. It's contained in an 8bit register starting at something like 0.80V for value 1 and ends at 1.52V at value 255. 1.52V is the max value it can hold purely because it's the point it runs out of numbers. If you look at the datasheet it actually lists out all the possible register values.
Ye , I kinda knew you were gonna say that, which is why I went to the Intel Live Chat this morning to check for myself, had a chat with one of theirs engineers, I asked him about it:-
So yes I'm going to take that 1.52v as being correct, as well as several other sources in various forums saying the same thing. Thats plenty enough proof for me over your "Urban Myth" statement.
Common sense tells you that you shouldn't be running it at that voltage for prolonged lengths of time anyway.
Don
So the Intel rep points you towards the data sheet which is incorrect. Do you not think that just highlights why this misinformation exists. You yourself have just admitted that common sense says you shouldn't run at that voltage, why is that? It's perfectly safe according to the Intel rep.
I remember when this first came up in an overclocking guide where the author said that 1.52V was the safe max according to the datasheet but later on in the guide he says that after 6 months at 1.5V his chip was no longer stable at the same settings

Sorry, but when you say things like that you can understand why people find it hard to believe anything you say. So far the only misinformation being given is from you, and I have no reason to believe you over an Intel Engineer.
As jokester has explained, the maximum VID a chip could leave the factory with is 1.52, because as some point in the design they had to specify the format for saving the VID to the chip and settled on 0.7 to 1.52 or whatever. I'd bet a lot of money though that the highest VID they actually end up putting in to the chips is way less than that (say 1.15, 1.2, something like that).
The stock clock speed and voltage is chosen to last a long time and have a vanishingly low error rate. Increase the volts = decrease the life of the product. There's no going around that.
As for a "max safe voltage", nobody can answer that, it probably depends on how long you want to keep the chip. Next time, a better question for an intel engineer might be "if I want to run my chip for 4 years 24/7, what's the max voltage I should use to have a 95% chance of not killing it?".
Is any of this really relevant though? in all but extreme cooling situations, where lets be honest most dont last long anyway, lidded or otherwise surly these things are going to give up due to heat way before you get close to 1.5v anyway arnt they?

Another thing to consider is, as current draw increases (via higher clock speeds), voltage tolerance decreases in an almost linear fashion. So 1.52v being perfectly safe at stock setting does not mean 1.52v is safe at say, 5Ghz, regardless of how well cooled your chip is.
Don
I've referenced the specific section of the spec to show that the 1.52V figure is not the max safe Vcore. Anyone can look at the datasheet and confirm that for themselves. As a comparison, here's the applicable section for the SB-E max safe Vcore value:-
http://www.intel.com/content/www/us/en/processors/core/core-i7-lga-2011-datasheet-vol-1.html
Page 55 Table 7-3 - Max VID register value 1.52V (it's exactly the same values for SB)
Page 60 Table 7-8 - Max Vcore 1.4V
Page 61 Table 7-9 - Max Vcore VID 1.35V
For Sandy Bridge-E Intel have stated max values for Vcore, not only that they have even stated that the maximum VID you will ever see is 1.35V for SB-E. That information is completely missing for SB, they only give the VID register values.

Mate I hate to be the one to tell you but you weren't talking to an intel "engineer". You were talking to a CSR.
Yeah....i expect all he did was google your question..
Anyways, back to the excitement and i gave the lid a quick lapping..
Got very bored and decided i'm not going to sit here all night so got it good enough (will give it some more 1200 on monday when the new paste's come) and give it a test..
room/case temps were about the same, maybe slightly hotter for the second test..
Before;
After;
So a good drop in temps and should see slight improvement when the liquid metal comes Monday!
