So I decided to try this whole delidding thing and prepared like a major surgical operation all of the tools I thought I would need:

1. https://www.amazon.com/gp/product/B079HDBYY3
2. https://www.amazon.com/gp/product/B008O9YIV6
3. https://www.amazon.com/gp/product/B0002UEN1U
4. https://www.amazon.com/gp/product/B07FM58Z42

And set about the project.

By the next morning I had reinstalled the cpu and was ready to go! So far I like what I see, with the exception that one single core seems to be running hot:

After about an hour of Prime95 I'm getting:

Not sure if I should delid it again of if this is pretty ok. Suggestions?

Those temps are fine under Prime 95... that program assaults any CPU/cooling system.  What are you using for a cooling solution?  You can also test with Cinebench, Realbench, Aida64, or even the sim if it is your most taxing program, to get a better idea of your real world use temps.  Curious how you have one core running hotter than the others... I've delidded several 8700K's and not seen the core temps that far apart, but then I don't use Prime 95 that much.  If you test with other programs please post back with your results.

Nice job!

Which version of Prime? Older versions didn't run AVX, newer versions do.

Did you test temps prior to determine how much lower the temp is? Otherwise just guessing. 

Re one hot core, not unusual... I'll nip off and test my 8700K and report back.

 

Re your choice to glue IHS back on... if you choose this method, it's imperative that you only use a slight smear of adhesive just in the corners. The less the better. If you don't, then you will be increasing the gap between IHS and die once more, and back where you started.

26.6

And previously ALL cores headed for 87-90 when I did 5ghz

8700K, no overclock, fans still on PWM so ignore temp, just as an example of my core variability...

 

57   56   60   62   54   57

If you want me to try at 5 GHz let me know.

Well, if it wont blow up your computer........ 🙂

An improvement then.  73.7 average across the cores.

What settings did you use when you ran Prime?

Although I'm running a delidded 7700k at 5KHz, the variations in core temp are large; ranging from 66c to 77c. Almost every cpu delid I've seen has this. I don't believe its an issue. They are also 'peak' max temps. The average temps are considerably lower.

 

At 5 GHz. 1.36v Max. 19C ambient. NH-D15S. I see...

71   65   73   76   64   68

Max temps, so brief spikes: 73   69   77   81   66   72

69.5 average across the cores.

My voltage will go lower, lost settings so just ran 5WO. 

Same sort of variation as HiFlyer but interesting your last core is always the hottest. Whereas my 4th core is always the hottest.

5 Kilohertz Dougal!!! I always knew you were in possession of alien tech.

I can get a solid 5.2GHz but just not happy to touch 85c!

I did cheat a wee bit by appying a negative 1 AVX offset;-)

KILOHERTZ though. You can change it to GHz if you like, but I know you are really an alien spy from Proxima Centauri!  😁
