For reference, here is the damage if anyone was interested. Using the link above, I've determined that the A25 and A26 VCC nodes are the ones in close proximity.


No worries! You actually asked that at a really good time - I was already going through Intel's data sheets looking for some info (that I didn't find), then saw your post.... cheers.gif

Don't bother responding unless you want me owning you some more. thumb.gif

Did you read his post? He commented on a delid Haswell being too hot, judging from his 2700K (that is NO HASWELL chip fgs). So yes, he should not comment.
Neither would I comment on the RPM of someones Porsche being to high, just because I incidently own a Diesel Land Rover that hits red at 3k.

Giving the advice that he needs to re-seat the IHS because he must have gotten it wrong, in this case, is not helpful!

Sheeshe...read the stuff before you post.

@OcN13: BTW, "own" me some more, m8. However, you are welcome to apologize to me.

Oh and thx @blaze2210 for reading the post wink.gif

I have this info in my post with delid pics in this thread, but if its useful..

In my case..

Asus Z87-pro C2 stepping board:
CPU Multiplier –45
BCLK - 100MHz (THIS IS NEW, always had on auto)
vCore - 1.35v
CPU VRIN Override LLC - Set to level 7
CPU VRIN Override Voltage - Set to 1.9
Ring Voltage - 1.3v (way LOWER than normal or auto before, old asus this had to be 1.36 with cpu at 1.29)
UNCORE – (42)
Turbo, C1E, C3, C6/C7 & EIST – Disabled (NEVER did this before)
HT: On

Ambient temp 21C, max temp between 89C and 91C with OCCT 4.x over 8 hours at this 1.35/1.30 voltage.. this on air.. NH-U14S.. (i had very similar results even with the H80i)..

With prime95 at similar volts i had gone from 98C pre-delid to 85C incidentally, so roughly a 13C drop.. all using CLU, some clu on the underside of the IHS and the thermal paste that came with the NH-U14S..

I briefly considered going to a dual radiator kraken x60.. but since suddenly after i got this new C2 board, redid everything my temps are pretty good for this voltage.. i may not need it.

I can go 8 hours with OCCT, but prime95 28.1 blend still craps out after 10 minutes though (another story).

I am a novice overclocker so this is probably a stupid question but why do you subtract the ambient temperature from the maximum core temp? I have been using CPUID HWMonitor and just assuming the temps it is showing me are representative of the max temp of the core relative to the manufactures recommended max operating temp. Should I be subtracting ambient temp from those numbers to determine my core temp?

^No, but good question!

The ambient is subtracted because with a typical cooling system on a CPU or GPU for example, temperatures scale linearly with ambient temp and can be measured as such;

If you have 20c ambients for example, some settings and a certain cooling solution could give you 70c CPU

if you have 30c ambients with the same, CPU would be at 80c

So you can measure this as ambient +50c, instead of just stating "70c", and it is easier to read and more adaptable depending on individual conditions

Everyone compares the actual core temp as read by those programs. So if someone says they were running Prime95 and their chip hit 80C, that means RealTemp/HWInfo/etc showed 80C. No one adjusts for ambient unless they are trying to show the affect of different cooling solutions (in a review, for example). If people mention ambient in a post, like the one above yours, it is usually just to provide a reference for the conditions they were operating in. Someone who has really low temps at stress testing may mention that it is because he lives in Finland and has the window open, so his ambients are -10C, which is going to lower the core temps as Cyro999 described.

Did another delid with a 4670k.
I used a blade with a metal Grip on one side. So you can apply more pressure when You cut between heatspeader and PCB.
Took me about 10 minutes to remove the heatspreader. I will apply Liquid Ultra between die and heatspeader as Liquid Metal is the only true solution for this.





I was a bit Temp limited so now I can try for 4.7 Ghz smile.gif

Woukd anyone be interested in de lidding mine if I send you a 4770k? I know if something went wrong I would be out but that's fibe. I'd rather send it to someone who has done ir before then myself . I have the CLU I would sebd along as well. Please pm me if you woukd do it. Woukd be awesome to have a delidded one

Sorry for the mis spelling was using my phone. Also I'd rather you be in the united states so shipping won't be so heavy
