Honestly, I don't hear many people who use their CPU warranty, but before lapping your CPU you should attempt to reapply your TIM with a different method, since your results are fairly skewed.

my I7 2600k same as yours!!
core 0 is like 10 degress cooler than the rest cores underload.
at idle, they don't have much difference, so my i7 has a concave die cast too?

should I do something as a workaround or I should send back to Intel and call it a detective CPU? Thanks

People barely use their own CPU warrenty? You sure? But after lapping and then in the future when something else went wrong (CPU defects come to surface) one can't RMA or return it because the warrenty is already voided?

Wait a second, does overclocking void CPU warrenty too? Can Intel really tell if you have OC'd it or not?

I'm glad I'm not alone! don't draw that conclusion yet though! We first need to confirm if our CPUs actually have IHS concaves... use any flatness mesuring tool (razor could work) with light to on the CPU to check.

If our CPUs appear to be flat or at least mostly flat, then Maybe it's our heatsink IHS. Check that out too.

Search through here a bit, you'll find this is not unusual. That does seem a high for your cooler, however.

With my scythe, I'll get 69, 78, 76, 76 running at 4.7ghz @ 1.365v after a few hours of small FFTs on prime 95.

Yes, overclocking does Void your warranty, but no they cannot tell whether you did or not unless it burns.

If it is Concave and you lap it you will see a huge Drop in temperature. You could Apply more paste and wait for it to cure and see if it helps.

Well, yeah, but they can tell if you lapped the CPU

Well, I don't have any sandpaper or whatever that's called, so I guess I'll check the IHS and maybe apply more paste/different method for the time being.

Okay this may sound a bit crazy but the difference in core temps may just be some weirdness with your temp sensors, my E7200 shows one at like 25C and other at 33 at idle and they don't get much closer until they get to the high 40's even then core 0 is always cooler, might not be a problem at all

Mine seems to be about the same, the Core 1 and 2 always run hot, it does not matter what method or amount was used. I did get temps to drop about 4C when I used Indigo Xtreme. Regardless I believe both the CPU and/or the heatsink are concave. So unless I either want to replace both or lap both I'll stick with the temps. I have been running 24/7 with temps between 35-68C. If I run Prime95 they will shoot up to 87C during 4hrs of Prime95.

Agreed. I actually feel comfortable with the temps. 1.325 vcore / 4.6gHZ 24/7 / 75c with prime, I barely hit 70c with IBT (8 threads with all of the ram memory). These temps won't be easily achieved if I game or multitask, so it's all good. Plus EIST is enabled, so I'll save power whenever I don't use the PC.

I feel lucky hitting 4.6ghz stable with 1.325v so I guess I'll stick with that now Quite pleased!
