7700k + CM 212 + Prime95 = 90C :(

[Ed1]

This is interesting while I was checking on alternatives to the pea size drop method for the thermal paste with respect to 212 LED I came across this review https://www.bit-tech.net/hardware/cooling/2017/01/11/cooler-master-hyper-212-led-review/2 for the 212 LED. Notice how far this 212 is from the 212X specially in the socket 2011 even an i32 beats it, I have no idea why most of the reviews which I read gave the 212 LED high marks and if memory serves me correctly in most places 212 LED was shown equal to a 212X or very close.

Anyway here is the latest result from using 2 new intake fans in the front and with existing 1 exhaust fan and 1 side panel fan. I also reapplied the thermal paste "Using a vertical line method" after using a special clearer on both the CPU and the heatsink to remove all oil.

Confirming yes it does make a difference Core1 is closer to Core0 but Core4 went crazier by 7C. My CPU is not HSF off I am frankly scared of it ever since the time of the ivy bridges.

Totally normal to have one core 7-10c hotter its just how they are laid out on die.
First, in bios make sure you have Asus enhancement disabled , right under AI OC tweaker, as that sets all core to max.
I can't tell from pic what your final Vcore is but at around 4.4 I bet you could be ok with 1.165-1.180v and if you decrease to 4.1 you really shouldn't need much, like 1.125-1.140v.

On that HS base you will need to add paste to between the pipes as those spaces need to be "prefilled" or normal application of paste would not spread it there and you will have air pockets.

If all else fails, it's time to upgrade to a dual tower (e.g. Raijintek Tisis, Thermalright Silver Arrow, Noctua NH-D15), massive single tower (Thermaltake Le Grand Macho) or double rad liquid cooler. Going by others' results with the 7700K and threads about the 212, it just seems that you may need better cooling for that CPU, barring delid.

 

[ozzy702]

First off, OP is running furmark along side p95 which is simply not a realistic usage. His case doesn't have enough air flow to keep up with the thermals so they just keep going up and up. Under that situation yes, the Cm 212 is simply not enough cooler given the case design and the fact you're pushing your GPU WAY past normal usage with furmark.

Monitor your temps under actual app usage and I'm sure you'll be fine.

Other options:

Get a bigger CPU Cooler

Get a better flowing case

Undervolt and or underclock your cpu

Delid CPU

It seems to me the OP has solved his problem: his worst case temps have gone from 102-103C to 89-90C. Real temps while gaming or using productivity apps will be way lower.

yes its much better than before the CPU is running at stock speeds but under voltaged by 0.040 and ASUS Turbo enhancement, etc disabled

The weird part is although Furmark and Prime 95 run fine together but games like kerbal space program keep on crashing does that mean the underclock is unstable?

I will try and add more voltage and test out the game again and again. I have also maxed out the number of fans that can be put inside the cabinet which makes my options limited for the future.

Honestly the OP should investigate what stock Vcore he can get. My chip isn't even great (4.9ghz requires 1.34v), but at stock 4.5 turbo I can get Prime 95 stability at 1.15vcore. Per my own investigation 1.15 vs 1.25vcore is easily a 10C difference.

I only caught this because Gigabyte's LLC is pretty bad and in full auto mode my chip will request 1.26v or so at stock, but under load on Prime 95, Vdroop is a whopping 0.1V. Thus by using some LLC and manual vCore, I was able to test at 1.15v and confirm stability.

If OP is willing to drop his vcore a bit you can see even lower temperatures. BTW below are my own stats regarding load vcore vs temperature. I delidded for a ~13C drop.

...I delidded for a ~13C drop.

Out of curiosity, what TIM did you use after delidding it? I'm about to do so myself and trying to figure out if my MX-4 is decent enough or if I should get something like liquid metal...

Well first thing, was it crashing before lowering voltage?
If it is crashing only after lowering by 0.040, then try 0.030, also how are you doing this, using offset of -0.040? or you set a manaul fixed voltage.

If your doing offset I would bump up LLC from auto to 1 or 2 notches, this will give better voltage load response , also see if there is a option for CPU power phase control and set it to auto> optimized.
That should help, don't max setting with extreme in a lot of bios options under CPU, power management, that will just raise temps and for stocks clocks is not needed at all.

So what you can do is first make a bios profile of saved settings now and then putting back the ones you adjusted as test, then it is easy to bring back what you had. you can make multiple profiles while your making adjustments.

The GPU is a 1080 ASUS ROG Strix 1080 factory OCed with three fans.

With that GPU, the heat is being dumped into the case. If enough fresh air isn't entering the case, and enough hot air exiting the case, it turns into a cycle of the CPU & GPU trying to cool themselves off with exhaust heat (running a cpu & gpu bench at the same time). The first minute or two of that you'll watch temps slowly climb, the GPU will then start to down clock automatically with the heat, and eventually you'll reach a kind of equilibrium where the GPU down clocks enough, heat is leaving the case through the actual case itself (hot to touch), and temps stop climbing within the case.

The cooling is almost certainly your issue. Those post-founder's-edition GPU's often times need a lot more care in case choice to work well. The reference cooler may have been a better choice; good luck with tinkering with extra fans. It should help!

Got contacted directly by Intel since I had lodged protest letter in their regional office. They have told me a engineer will come and take note of the temperature spike and if it cant run within specified parameters on stock with stock heat-sink they will give me a replacement.

That is good news but I will have to find some stock heat sink now whatever that means

 

[imported_JohnJohn]

UPDATE: Sorry for waking up this dead thread but someone from Intel came to check the 7700K out and I showed him the high MAX temperature to which after about 10mins of testing responded by telling me to stay stock forever and that MAX was just a result of a spike and the CPU's throttle temperature was higher so I will be fine till I am in stock.

It does seem the 212 had less to do with it than the lemon CPU itself, I have ordered a h55 AIO to see if that helps with the spikes never did I think I would return to water cooling after spending tons on a custom loop

 

[imported_JohnJohn]

UPDATE2 "Last Update":- My CPU saga continued getting a AIO does not help a lot I was forced to buy a delidding kit and open the 7700. The thermal compound inside seemed to have some weird tiny bubbles on the surface wiping it off and using some silicon based thermal paste did the trick though its purring like a kitten and with much better temps almost 10-15C lower.

The moral of the story is get something like HEDT next time which has a proper heat conductor under the lid.

 

[imported_bman]

Does that mean you are still at 80C-75C at stock frequencies?

Since you already went through the trouble of delidding your CPU buying and applying some better thermal compound might make sense, Coollaboratory Liquid Ultra TIM is ideal for delidded CPUs.

 

[DrMrLordX]

Good luck getting a "proper heat conducter under the lid" since Intel puts the TIM on Skylake-X dice just the same as they do Kabylake.
