10900k temps and core to core delta

[steverebo]

so I decided to grab a 10900k for my new build judge all you want

Im busy playing with it and have found it very good for overclocking but at 1.345V 5.2ghz all cores if I run prime 95 avx small fit's it hits over 100 degrees instantly. Anyone else with one of these experiencing this just want to know its normal and not my waterblock mount???

Also I've noticed a core to core delta of a whopping 20 degrees

Is this normal?

Just want to judge my experience against someone else to make sure everything is normal and I've not got any loop issues

Running Aida64 cpu, FPU, cache stress test 1 hr with Valley in background
Cpu package 93 degrees, core temps 74 74 78 76 86 93 89 80 81 73

Running 3 x 360 rads in a lian li 011 dynamic xl D5 pump

Yeah that's what I thought, at idle all core drop down to high 30's low 40's without any real difference in core delta

Does using konductanaught on cpu ihs void warranty?

 

[steverebo]

Would a 20 degree core delta be grounds for an rma? Most I have ever seen is 7 or 8 degrees

Im going to drain the loop and re-apply my thermal paste and block and see if that makes a difference.

I did the old spread it thinly and evenly method with my thermal grizzly might try the X method and see if that makes a difference

Ok guys so I thought YOLO and went for it and I delidded my 10900k and applied liquid metal and what a differnece!!!!!!

Same test as before aida64 with valley in the background my temps are now average:
Cpu package 76 core temps 65 65 68 67 68 70 66 68 62 64

Previous

Cpu package 93 core temps 74 74 78 76 86 93 89 80 81 73
No more core to core delta and roughly a 20 degree improvement in temps!!!!!

This is without letting my liquid metal and kryonaught cure so temps should improve further

The indium solder is so soft i could use my finger nails and then some 3000 grit sandpaper to finish it off.

AVX workloads are still way too much for this chip even delidded it hits 100 degrees prime 95 small fft.

I get whea errors in first 10 mins of prime 95 AVX small fft, occt avx2 with temps in high 90's/100+ so errors are likely temp related.

What would you guys say is gold standard for stability testing?

Does errors in avx mean my system will be unstable?

I've got it running 5.2 all core 1.35v 46 uncore

Done 4 hours realbench stress test
1hr prime 95 small fft in place (12/12) non avx
12 runs of cinebench r20
12 hours occt non avx
4 hours aida 64 cpu, fpu, cache
