Well now that im all all finished with my build I tested a few auto overclock settings and am pretty happy over all.
Right now I have it selected to extreme profile #1 which auto set my 8700k to 5GHz at 1.35v and I am getting 52c idle and about 80c max temp but am spiking to 85-87c on 2-3 cores but then quickly drops back down to 80c? This is when the cpu is under extreme full load using CPUZ bench tool.Only using a Hyper 212 Evo Plus. Not sure what everyone was talking about when they were claiming that the cpu gets hot and needs extreme cooling?Anyways I am going to change back the bios settings and run at stock speeds for now,not that I am worried about temps but just feel that the cpu is fast enough at stock speeds for me.

I think its throttling.

Re-lid complete. Bench testing went fine. Temps were slowly climbing, but that was to be expected because I had an old i5 stock HSF on it. I guess I'll rinse the radiator, pump, reservoir, and water blocks out and finish the build over the weekend.

Apparently, I bought some Coollaboratory Liquid Ultra a while ago (I found it just yesterday), and I purchased some Conductonaut recently specifically for delidding. I'm practicing on the G4400 right now. I removed the IHS, but I've got some thoughts that are making me wait a tiny bit...

• What's the best method for putting the IHS back on? I've seen some use super glue, but I've also heard that it's not really the best method, because if you remove the IHS again, you could damage the processor if the glue holds too well. I've also seen some use high-temp gasket sealant, but there are disagreements over how to put it on. Some apply it just like the original material (all the way around with a slight gap). I've seen some that just put a dab in all four corners (like they do with super glue). I've seen some people that say that you should use a syringe to put the sealant on to avoid putting too much on.
• How do you know what's too much TIM? When you're dealing with a conductive TIM that's near sensitive electronics, you don't want too much. Since I'm pretty new to this stuff, I don't know a ton about its viscosity, and essentially, how much material looks right. I've also seen most videos put the TIM on both the die and the IHS.

I did buy some 1mm syringes to test with, and they'll be here today.

Well, you don't even have to. You can just let sit on there, but keep in mind that it will slide around a ton while you try to clamp the CPU in. This time I used gasket sealant. I just put 4 tiny dots on each corner of the IHS and then clamped it down (because I was using a Rockit 88). You aren't going for an air tight seal (note that even the stock stuff has a little gap where none is applied). The only purpose is to hold it in place long enough to clamp it down. It isn't going anywhere. Last time I did one, I didn't even glue it, but it was a pain to mount due to that. I know that Rockit even suggests superglue, but I feel safer with the gasket stuff. The tool makes the whole process a lot easier compared to my last no glue, razor blade one.

For the liquid metal TIMs, you just put a tiny, tiny dot, spread it, and add more as needed. What you want is a thin layer coating the whole thing. Just keep brushing it to spread it, and if you can't get it to reach the edge without getting a gap in it, add ever so slightly more until you can cover the whole surface without any of the underlying material showing through. You won't need any appreciable thickness, but you will want to have total coverage. Just start small, and add tiny amounts as required until you have brushed the whole surface covered. It will look a little lumpy, but there is no helping that. It will be ok.

The pics are missing?

Just noticed you have the same case as me. How are you finding it?

Can you see the pictures now? Also yes I love the case so far. I have had it like a little over a year and it has seen 4 different builds and upgrades. I was going to get the Corsair Carbide Full Atx Case today but it got put on hold till I can make up my mind on if I wanna spend another $130 bucks on a new case or cooling.I guess the only thing I kinda dont like about it is the fact that the USB ports on the front are upside down which can be a hassle sometimes plugging in controllers and what not.

Yeah that is how I linked it on the post.. Thanks for posting the pictures and sorry for the bad quality. I only have a i phone to take them with. That last picture was supposed to be my CPUZ screen shot not that blurry cpu shot..

Your heat spreader looks much different than mine. Here is mine being glued back on. I didn't go for a pure mirror finish, but it's pretty reflective. Note that the bolt is centered on the IHS, and the reason it looks like it is on the corner is that you're actually seeing a reflection going up in to the white plastic clamp. Half of it is the bolt, and then the other half is the reflection.

I like the way the EK waterblock mounts. There is spring tension, and you crank the caps down all the way. You know you have turned them far enough because they bottom out on the threads and stop. I've used mounting systems in the past that were a bit of a guessing game.

Hey guys, this is my cpu on stock, no MCE.

Somebody told me that there should never be that much diff between cores at any time.
Never heard about it. Is that so?

Thanks for the advice. I'm using the same Rockit 88 tool. I think I saw it on an episode of Linus Tech Tips, and it looked easy enough! I remember trying the vice-n-wood method on my 6700k, and I couldn't really get it off... or more like I wasn't willing to hit it harder.

Are you planning on letting your sealant cure for the full 24 hours?

If you look at the average temps they are all within a few degrees of each other. You are always going to get differences in a snapshot of time because at that particular time that core may be doing something a little more to stress it.

 

[Ferzerp]

No need. I gave it 3 or so. Remember, it isn’t doing much. It isn’t under any strain except while you clamp down on the cpu. People worry about gluing the thing back on far too much like it is going to some how come off when it is squeezed on by both the clamp and the pressure from the heat sink. It’s not going anywhere once installed.

If I were making a gasket, sure 24 hours. But when just tacking metal to a PCs long enough to put it in the socket? Nah.

 

[Ferzerp]

This isn’t why. The cores always vary because they aren’t all thermally identical due to their location. The ones sandwiched between other loaded cores will be warmer. The ones near fewer cores and adjacent to “dark silicon” that isn’t doing anything (like an inactive igpu) will be coolest. You can certainly load them all equally enough that they generate the same heat. It’s just the physical layout causing different temps.

The relative temps under full load will always be roughly the same (given equal cooling), and which cores are hottest will also be the same across all samples.

The two middle cores will always run hottest, probably followed by the two on the left, and then the rightmost two will be coolest assuming the igpu isn’t in use. Depending on the memory IO at the time, the IO area could either act as a heat source (if it is hot), making the top row hotter, or a heat sink if it is cool (making the top row cooler than the bottom which is adjacent to just air beside it).

Edit: that said, I can’t make the particular example fit this model. If it weren’t for that core 6 it would fit pretty well with upper left being core 1, lower left being 2, etc on to lower right being 6. Is the igpu active and hot near core 6? Is there a heat sink mount issue? Am I even correct on my mapping of the cores? The variance in temps, ignoring core 6 seems pretty standard.

What are you using to cool your cpu with again? Hyper 212 Evo right? Those temps seem awfully high to me. Im also running stock on my 212 Evo and I am getting 29c-42c running the same 3 programs. you might wanna try adding some more thermal paste or remounting your heatsink or something. You should not be hitting 60c-70c on any cores idling with a few monitor programs running.

What he is describing is exactly why people delid Intel processors. The problem isn't that the cores themselves produce more heat, it's that there is too much variance in the way they assemble their TIM + IHS combination which results in some having a perfectly serviceable IHS gap (like yours, most likely) and others having... less than optimal gaps. Resulting in higher temperatures despite identical cooling.

His temps are still perfectly safe and well within Intel's recommended range.

 

[Justinbaileyman]

Hmmm.. I think I might be having an issue with my cpu now. In Hardware monitor from the same people who made CPUZ, it is showing core 2 with the word "temporary"? didnt really notice this last night. is this just a bug in the software cause Windows 10 task manager monitor is showing all core activated and running fine and so is CPUZ.

Edit: did a reboot into bios and set Active cores to 6 manually saved exited and booted into windows and now Hardware monitor is showing fan 1 , Vin7 ,Vid #0 , and system agent 0 with the wording TRIAL?
Is this something I need to worry about?

 

[Ferzerp]

You downloaded hwmonitorpro. It isn’t unrestricted free software, so it is nagging you.

Haven't really found a straight answer about MCE. Has anyone used non K Coffee Lake with MCE enabled/On with stability? If so, what motherboard are you using and what temps, voltages, benches are you getting?

MCE should not work on non-K.

 

[LTC8K6]

MCE should not work on non-K.

Yeah, I was hoping it would be like Haswell, but it doesn't look like it...

I must have won the Silicon lottery of something cause I have my cpu fully pegged at 100% load encoding movies right now and the temp is staying below 42c for the last 2 hours or so.Heck I bet I could lower temps even more setting my 8700k TDP to 65w. I thought maybe hwmonitor was faulty but my heatsink pipes and fins and heatsink base are all like ice cold to the touch.So far I am extremely happy with my purchase.Thank you guys for pushing me on waiting and helping me to be patient to buy my RIG piece by piece so I was able to build my baby. It really is everything I was hoping for and more. First time I have every had a top of the line motherboard like this too. Its very hypnotizing watching the light show it puts on for me from the built in RGB's. I hope the rest of you guys luck out and get good chips to!!

There's AIDA stability stress in the background, that's not idle it's 100% load.

oh ok gotcha.. was a bit worried for you that you got a really bad defunked chip.Makes sense!!

I don't want to be a wet blanket, but have you run a benchmark to be sure its not throttling ? 42c full load sounds way too cool with a 212 EVO@100% load. I can't even get that with a stock 6700k and a 212 EVO

 

[Justinbaileyman]

I only ran Prime Small fft's for a couple hours and CPUZ Stress Test for a couple of hours. Also been running Handbrake Non stop since last night. The only thing that makes my CPU Spike in temps is Prime. Is there anything else I should try running?? I guess I should note I do have my fans running full blast in my case and on my 212 Evo.
