What’s wrong with I7-7700K and its temperature’s…

[Sp1]

Hello Everyone,

I know this is not directly Asus motherboard related but I can use some tips from you guys.

I build myself a new PC around 50 days ago, CPU is I7-7700K and motherboard Asus Z270G and the cooler is a Cryorig H7. The other components are not relevant for this topic I guess but here is the build: https://pcpartpicker.com/b/MV7WGX and a short video of the rig: https://www.youtube.com/watch?v=fddIUJgDw3M

First couple weeks the temps where fine, till I start playing some games, and temperatures where hitting to 88C, I did benchmark but not heavily, so I changed the vcore to 1.250 volts manually in UEFI since the motherboard was putting it on 1.365 volts. Also changed the fan on Cryorig H7 to another one with more static pressure, cfm and higher RPM speed. Temps went to 80C after all this. This is on a CPU without any form of overclocking.

Last 2 weeks we have nice weather in the Netherlands and temperatures started to rise outside, but temperatures also started to rise on my CPU. So to be sure I downloaded Realbench and did a stress test, believe me guys, I knew temperature’s where bad on a I7-7700k but this bad? I had to break the stress test because the CPU was hitting 94C.

I did build a lot PC’s years ago but not last decade or two 😛 so I might have lose my touch, I decided to reseat the cooler and this time I used Noctua NT-H1 as heat sink compound instead of Cryorig’s CP5, and this didn’t changed much, only 2C less with stress test, had to break the stress test again, I don’t want to test its limits.

So far the trouble I got, now the planned solution:
I ordered a delid kit from Rockit Cool and received it 2 days ago. Also ordered a Corsair H100i v2 and Coollaboratory Liquid Ultra, these will arrive tomorrow or Monday.

The reason for 240mm AIO is the ecstatic’s and limited room I got in my case. I was thinking to get NZXT x52 but a friend of my told me he was not happy with CAM software, so after reading some reviews decided to get the H100i v2.

Than as always I was being stupid not checking here to see how my Z270G Strix will work with Corsair’s Link software, now I see there are some issues with this AIO on Asus boards, I can figure out how to fix that I guess.

I wish I could test the temperatures after the delid with the Cryorig but my motherboard needs to get out the case each time I do anything to the cpu, so I am not going to do that, the motherboard did already get in and out too many times for my taste.

I would really appreciate if you guys have any tips for me on Z270G UEFI settings and so on.. I don’t know what temperatures I will see, but I am sure it will drop some.

RMA is not an option, I don’t want to wait till Intel respond to anything, while we speak of Intel… WTF is wrong with the TIM they used?

Haha yeah it does pretty good. 🙂

Once you delid and get your AIO you should be able to do some overclocking.

I really hope so Nate152, anything around 4.9GHz is more than enough for me, I don’t need to set a record 😛

Meanwhile I got a mail from vendor and thermal compound and H100i will arrive tomorrow at my door, unfortunately I don’t have time till Friday so it has to wait, I don’t want do things in hurry and ruin my CPU.

Also tried Corsair LINK today, it is reading everything but also can’t control anything, which I don’t mind, UEFI handling fan speeds is for me better option.
Made my own case image with Z270G and some other stuff I have in there, not to fancy but will do the job:


This made me realize my HDD temperatures, these are pretty high back there...

I suggest you run corsair link for the CPU cooler and AI Suite 3 for the case fans. They work well together. At least for me they do. I like being able to adjust my corsair and case fan settings on the fly better. AI Suite doesn't run my H115i as well as Link does.

Also as noted above, if you are comfortable de=lidding your 7700k, do it. It's worth 20c max load temp...maybe more. Intel's TIM on the Kaby Lake chips is very poor in my opinion.

I didn’t realize that topic has 2 pages already mdzcpa, sorry about that.
I read a lot lately about Al Suite 3 and Link and to be honest it is to dodgy for my taste, also when I uninstalled Al Suite 3 my temperatures where suddenly better, it was messing up I think.

May I ask you where you connected the Pump header from H115i to the motherboard? CPU_Fan or CPU-Pump?

Like I said above I am happy when UEFI controls my fan not that I think that Al Suite 3 is unreliable, but I don’t trust windows.

I sure will delid, I have Rock it tool here waiting on liquid metal :cool:

Hi there, i have similar config as yours. H80i v2, z270f and i7 7700k. According to Corsair offical forums we need to connect Pump header to CPU_FAN header on mobo. And from bios we need to set CPU FAN to FULL SPEED.

Nice !

Everything looks good and nothing wrong with the bios controlling your fans. As you say your drive temps might be a little high but they're not critical, I have a fan blowing over my Toshiba vx500 ssd and temp is 30c.

I am not worried about the Samsung Evo 960 M.2 that one is always below 40C, but I never paid attention to 3.5 inch HDD drives I have (got 3 in there), Toshiba one hits 50C as you see, I can fix that, I will have some Fans left over after mounting H100i so that problem will be solved too 😄

While I was at work (evening shift) the Corsair H100i v2 was delivered, I was home around 23:40 and my hands started to itch little bit, so around 2:00 midnight I started to work on my PC, just could not wait till Friday 😄

Spoiler alert: Was I happy with the results? Yes, but it is not what I was hoping for.


Took out the motherboard and grabbed everything together:



Delided the i7700K, the compound Intel used was dry and feel like mud from a beauty salon:



Cleaned up everything:



Applied the liquid metal ultra from CoolLaboratory :



Glued back together with Loctite 5926 Blue Silicon only at four corners and waited an hour:



Installed the Corsair H100i V2:





After little cable management (again…) turned on the PC, but I didn’t want to fool myself by directly doing a stress test while water temperature was low, so fired up Battlefield 1 and played for almost a hour. Ambient temperature was 0.5C lower than last time so it was around 22.5C.

I kept everything as last test, did not clocked the CPU and keep the voltage same, the idle temperature was 9C lower.

Corsair LINK is in balanced mode and didn’t change the pump and fan curves, here a screenshot just before stress test:


After RealBench stress test, max temperature was 67C, this is 15C lower than before delid and AIO, but average temperature was only 42C this is 29C lower than last time, so there was definitely a huge improvement.

Here RealBench result:


HWinfo:


LINK screenshot just after stress test, water temperature raised up from 29.1C to 35.7C the Corsair fans stayed under 2000Rpm which was not so loud, if I test the fans on full speeds they are LOUD so I have to look in to that, maybe another fans with Push/Pull configuration.




Test was done with all panels on, and here is the end result at the rig, I was surprised with the looks, I did like the air cooler with the Enermax fan on it, but this looks nice too, in person it looks a lot nicer than the picture:



I hope I didn’t annoy you guys with all these pictures and story, I like to share my experiences. I am really tired now, I hope I didn’t make too many language mistakes, going to sleep now 😛

Nice to see you have beat the CPU!
Im 100% in agreement with you on AI Suite. Great idea, poor execution. Causes more problems than any solutions it offers.

Yes I beat it literally with a Rock It tool lol 😉
I loved Al Suite to be honest, it had the looks and functionality IF it worked, it was weird to get better temperatures after uninstalling it and somehow it wouldn't save its settings and such.

Nice going ! 🙂

Thanks Nate152, I was hoping for better results, at least 20C drop since I went for delid and AIO but the average temps are significantly better, I do reset HWmonitor after each test.
