Delidded i7-8700K [Update]

Hi guys..

 

Earlier I was having nice temps on my 8700K at 4.7 GHz 1.2v all core AVX = 0

 

But lately, in last 2 months, its temps keep rising slowly but steady, also because the climate here as a tropical region is relatively hot.. I decided to delid my CPU to improve anything related to it.

 

I used Der8auer DDM2 to get the delidding process brief enough for me as this is my very first delidding attempt, and the tool didn't dissapoint me, it was effortless..

Delidding is in progress..

 

 

After I took the IHS off of the CPU, I was surprised by how bad the stock TIM is.. I saw many youtube videos about delidding 8700K and saw how their stock TIM are, compared to what I found on my own 8700K I think I have the worst TIM I've ever seen. This is what I found, the stock TIM was dried out so bad..

I cleaned as much as I can with alcohol, I scrapped the black silicon with ID card as best as I can and cleaned it with alchohol. Unfortunately I forgot to take picture of how it looks after I cleaned it.

I replace the stock TIM with Noctua NT-H1 as it's the only TIM i have in stock, I won't bother to get LM at this stage, even more after I found how the stock TIM condition is. So I will just replace it with something better than the original TIM before I try LM. I applied NT-H1 by spreading it with spatula I got from TG Kryonaut.

 

I didn't seal the IHS to the CPU PCB because I will use LM in the future.

I put the CPU on the socket then I put the IHS onto it by lined it up to the trace of its silicon I cleaned before, then I just secured it with the stock CPU retention tool.

 

These are the temps before and after delid under 26C ambient temperature and NH-D15 CPU cooler. The pics order is before and after delid.

The difference by using the NT-H1 is 8C lower after delid, both the average and peak temps. So it's kind of slightly worse than what I expected. I'm expecting around 10-12C lower by using a better TIM, and 18-20C lower by using LM (I will try this in the future). 

 

In the 1st 30 minutes stress test the difference was solid 10C lower, but entering 45 minutes it started to climb up to become only 8C lower.

 

QUESTION:

Does it mean there is something wrong with my delid or is it normal for a better TIM than the Intel's stock TIM?

Or should I have just went stright up to the LM instead?

Difference seems fine given your low voltage, delidding shows bigger gap when you're pushing higher voltages as the thermal transfer gets limited quite quickly.

Then I should just try to push it to 5GHz or more slowly?

 

Before delid this CPU needs 1.31v for 4.9GHz, and never able to get 5GHz between 1.31-1.38v, I was not brave enough to go higher than 1.38v back then when I pushed it. So I stayed at 4.7/4.8GHz, but now I think I will try again to acheive 5GHz and see how it will behave..

Did you remove the black adhesive?

 

A big part of delidding is bringing the ihs closer to the die.

 

And yes, LM will yield better results.

 

8c improvement at load is already very significant.

Yes I did. I scrapped it with ID card then I cleaned it with 70% alcohol.

 

8C improvement is considered as good for a paste?

 

Is my expectation of 18-20C improvement with LM too high?

I all depends how bad the original TIM was.

 

I'd say 10-15c with delid LM is a realistic goal, with 20c being in cases with extremely poor original TIM.

 

I got around 15c improvement.

The stock TIM was really bad, it was dried out. Idk if isolated TIM like this can turn bad like that

15-20c with LM, 10-15c with new paste, both with silicon removed, this is only for high voltage cases though like 1.35v+. 8c seems quite good to me considering that was at 1.2v.

I'm curious why when I stress tested it, it was solid 10C lower than before delid, but slowly it climbed up again until it was 8C lower and stay there. Any thoughts?

It's pretty normal for that to happen.

I'll try to push it again as far as it can go. Currently it improved from before where it run 4.8GHz at 1.27v, now only need 1.22v, and it was 4.9GHz at 1.31v, now it stable at 1.27v.

 

I'm pushing it for 5GHz at the moment from unable to achieve before, we'll see..

What are you using? One of the better pastes than intel stock TIM or LM?

Thermal grizzly conductonaut between die and Ihs, and Cryroig CP7 between ihs and cooler.

 

In Realbench it would tap out at 95c after a few hours at 1.355v (1.32v actual under load accounting for vdroop)

 

And only around 80 after delid.

This is the temps for 4.9GHz 1.27v after 30 minutes stress test,

 

RealBench-20190313173412.thumb.png.6ac0b36d3cb0b54cacab756ace549c6b.png

 

It's the same temps as before delid,

 

4.7GHz, 1.2v, 84C max, 78C avg before delid vs 4.9GHz, 1.27v, 84C max, 77C avg after delid.

 

So this is kind of seal of prove for me that deliding not only make temps lower but also make CPU perform faster at certain targeted temps and allows lower voltages.

Edit: NVM, saw frequency/voltage differences

 

I was able to get 5.0ghz with a few less mv and also was able to actually not thermal throttle after delid.

I tried for 5GHz all the way through between 1.27-1.36v still can't get it done, the 1.36v brings it up to 90C. Just like before delid at the same voltage.

 

It might be the chassis air flow restriction.

my PC was going unstable sometimes because of the CPU temperature, so I just delided my 6700K this weekend, OC @4,5Ghz for 1.255v. It was throttling up to 90°C for a few millisecond and had an average 75°C in game

 

now without touching any settings it's around 45°C iddle and 55°C in game.

 

I used liquidmetal on the die and gelid between the CPU and cooler (Lepa AquaChanger 240)

 

I'm very glad. Anyway, I'm quite impressed by the temps you've got, nice cooling !

UPDATE!

 

Today I stepped up the level on improving my CPU thermal by using TG Conductonaut LM and Kryonaut under and over the CPU IHS.

 

As on the original post above, before delid I used the Kryonaut between IHS and NH-D15. After Delid I replaced the original Intel TIM under the IHS with NT-H1 also between the IHS and the cooler with NT-H1. The thermals was improved 8C lower under 1 hour Realbench stress test 4.7GHz, 1.2v, AVX=0, 100% intake system fan speed.

 

It also improved the voltage for 4.8GHz at 1.27 volts before delid to 1.22 volts delidded, but unfortunately it wasn't hold for long. After another several stress testings I have to go back to 1.27 volts for 4.8GHz.

 

So I stress tested it 4.8GHz at 1.27v, AVX=0 for 1 hours with Realbench.

Low thermal recepies..


The result under 26C ambient temperature was really surprised me. Here it is..

 

Idle 4.8GHz, 1.27v, AVX=0, NT-H1 under the IHS and between the IHS and NH-D15:

This is after I applied the Thermal Grizzly.

This is impresive, I almost cannot belive it. The improvement was from 92C at 100% intake fan speed down to 77C at 50% fan speed was really impresive with 15C lower, considering the case is known to have bad air flow (Enthoo Evolv ITX), the difference at same 50% intake fan speed was 17C lower. Note that this was the improvement between different TIM both after delid.

 

Now my PC is dead silent with the intake fans runs at 1000 RPM most of the time, 1500 RPM for over 75C, and 100% speed for over 85C, while the NH-D15 now also runs at low RPM most of the time. I'm very happy with this..

 

I will test with the same OC setting as before delid with the crappy intel TIM under IHS and Kryonaut between IHS and NH-D15, 4.7GHz, 1.2v, AVX=0, 100% intake fan speed. I wonder if it will output bigger margin compared to this 4.8GHz 1.27v OC settings.

Difference seems fine given your low voltage, delidding shows bigger gap when you're pushing higher voltages as the thermal transfer gets limited quite quickly.

Hey, you were right. The higher the voltage, the bigger the margin.

I tested and compare between 4.7GHz 1.2v before and after delid and 4.8GHz 1.27v also before and after delid.

 

The previous tests for 4.7GHz 1.2v before delid and after it, using NT-H1 TIM gave me 8C cooler.

I just tested again for the same setting but using LM and Kryonaut and lower intake fan speed, the difference was 15C between before delid (84C) and after delid with LM (69C), and only 7C between after delid with NT-H1 (76C) and with LM (69C) full load 1 hr Realbench stress test.

 

Idle 4.7GHz, 1.2v, 100% intake system fan speed, LM.
