post #18331 of 33558
Not sure what you are talking about, but my 2500k seems to run hotter than almost everyone else's, unless they fake things.....

75c at 4.5ghz on my H100, 88c at 5ghz on my H100.

Going to say i mounted things wrong too?


I really think intel has lost consistency across the board since SB was released.

Now, take my AMD setup.... i have a Coolit ECO ALC on that, running 4.2ghz, it idles at 22c... and reaches 45c maximum.....
At 4.5ghz, it was stable through benchmarks hitting 53c.



Just saying....

I'll just say, HEAT is not the same thing as TEMP.
AMD sensors report temps differently than Intel, 53c on AMD is Intel's equivalent of 95c. thumb.gif

62c (Phenom II) is intel's 98c...

Well, my point still stands...95c is pretty safe for Ivy. 98c would be terrible for SB but for Ivy it's slightly hot.

...finally, tried 'direct-die' - without stand-offs, just experimenting with torque-down pressures for good pin contact until clean boot and dual channel stress testing worked - saved another 2 - 3C , but as temps were low enough already and I'm still planning to try other water blocks arrangements, I reverted back to the lapped-IHS.

...If I would have made a vid showing initial temp drops from stock, the drop would not have been as significant (though still around 18 C+ w/ CL-U) as when comparing initial 'stock' vs 'final' config which would show a drop of more than 30 C, 'all in' - even though both are true...still, delidding brought the single biggest drop, all else being equal. smile.gif
post #18337 of 33558
A couple things.

The guy in the video remounted his cooler a half dozen times and every time the difference in core temps was still in the ballpark of 30C. I've seen some really uneven IHS mounts so that doesn't surprise me.

Watching other people delid is painful for me. I've delidded 3 times now, it takes about a minute. But requires a fresh razorblade and some hair on your junk.

Recon I'm not sure what you're talking about with your SB and temps. What TD was talking about is the difference in core temps on the same chip at the same frequency. If you have a difference of 33C between core #0 and core #3 then chances are you mounted your cooler funky. However, Ivy bridge, it is possible that you remount your cooler a dozen times trying to fix the problem, but you can't because Intel mounted the IHS unevenly.
post #18338 of 33558
One of my cores is always around 5-10c hotter than the one below it, and the next core down is always 10c hotter than the other 2, this happened with my Noctua NH-U9B-SE2 and this H100, but i am stuck with this problem as SB is soldered frown.gif

...as this is SB rather than Ivy (w.iGPU, some cores get naturally hotter) this sounds indeed like a slightly crooked IHS from the factory or something...have seen that before...ditto for slightly crooked CPU latch mechanisms...once thing you may want to try is to get 'pressure paper' from the store to get an actual imprint of the contact patterns...that may help to define next potential steps

Unfortunately that seems pretty common with Sandys. The two I owned had a 8C-12C difference between the hottest and coolest cores. I remember on the first one it freaked me out and I spent about 2 hours scouring forums trying to find a fix. Then a bunch of people assured me that it was normal.
