Insane temps for new 8700k

[bewong97]

After getting the system to post, I decided to check the temps. After one minute of idling in windows my temperatures were in the 70's to 80's(saw it at 30s in the uefi bios but spiked really high). I haven't tried overclocking it and practically didn't touch anything in the bios besides getting rid of the cpu fan error. After shutting it down, everytime i boot up into bios i see that its running at 70's C. At this point i took the cooler off and touched the cpu to see if it was hot or not. it was barely warm if i had to describe it.

The parts that I currently have are:
8700k + Maximus X Hero (Wi-Fi ac)
16gb corsair vengeance 3000mhz (running at 2100 right now)
Bequiet! dark rock pro 3 cpu cooler.

I tried re installing the cpu itself, remounting the cpu cooler, resetting bios settings, clearin cmos, and i've updated the bios. nothing had worked so far so hopefully someone can help me out here. Im just confused as heck right now.

sounds like something isn't right with your cpu cooler.

 

[terry4536]

I agree, it sounds like the CPU cooler isn't seating correctly. What thermal paste are you using?

 

[bewong97]

Im using the artic silver 5 thermal paste and im putting it on using the line method.

 

[bewong97]

So i just tested the 8700k with another cooler at stock. It gave the same high 70's temperatures. What should I do now? I was thinking that maybe the voltages are too high but that doesnt seem like its it.

 

[terry4536]

I generally use a BB sized dot in the middle, but as long as you get good coverage that is what matters.

That leaves the cooler mount installation. Check the instructions for anything that may cause a loose installation. I don't have any experience with that particular brand of cooler. But in general, cooler mounts are a pain.

Do you have another CPU cooler that you can try?

I suppose it is possible (unlikely) that the motherboard is defective or that the surface of the CPU or cooler isn't flat. If all else fails, replace the CPU cooler.

 

[terry4536]

Is this a new CPU on an existing motherboard? If so can you try the cooler on the previous CPU?

 

[13thmonkey]

That high must be a pressure or a voltage issue, not a thermal paste issue. Having no thermal paste will only be 10-20C above optimal, having really badly applied paste 10C up from optimal.

 

[terry4536]

You mentioned getting rid of a CPU fan error. Are the CPU cooler fans running properly?

 

[bewong97]

This is a new cpu on a new motherboard. I tried another cooler and that gave me the same results.

 

[terry4536]

That tends to rule out the cooler. You can examine the CPU for flatness with a straight ruler from different angles (use a light source behind the ruler) and look for a gap.

The motherboard would be difficult to test. Switching out the CPU is about the only test I can think of. Even an IR thermal sensor is going to of little help. So the only effective means would be to switch out the motherboard.

The last thing I can think of would be switch out both the CPU and motherboard. This makes sense in particular if you are getting close to end of the return period.

Having a defective motherboard or CPU for this issue is not common.

7700k, and 8700k both run hot and using 3000 ram XMP profile are known to heat up the cpus even more on some boards. You need to delid.

That would invalidate any warranty. Plus, I doubt that it succeed in correcting the issue.

I don't know if the XMP setting has anything to do with it. But it is easy to eliminate, by setting to a lower frequency.

What a great sense of humor that you have?....

CPU-Id, What is your voltage?

 

[bewong97]

So I did some testing over night and got some results. Whenever I use the clear cmos button at the back of the motherboard, it starts up, shuts down for 1-3 seconds and starts up again(guessing its a restart for the bios or something). It boots into windows fine, no problem at all.

This shows the temps when i do a cmos reset

Now after shutting down the system when the temps are i guess 'ok' compared to before, it does the startup-shutdown-startup cycle again. Booting up into windows I then check the temps and here it is.
https://gyazo.com/272f59905ad7a1bf8f9fd97c9c61b0ab

After a good 3-5 minutes idling at 60-70C the system then freezes, not even a blue screen or black screen. It just freezes and nothing is movable.

Another thing that I noticed was everytime i touched anything in the bios it would result in temps in the 60-70C. The things that I did were turning off Asus MCE, lowering vcore and decreasing the multiplier.

So im guessing the problem is from my Maximus X Hero? Cause if it was the cpu's problem wouldn't it be running hot all the time?

 

[nikoli707]

what does cpuz/hwmonitor report your vcore to be?

 

[bewong97]

what does cpuz/hwmonitor report your vcore to be?

Its around 0.6-0.7 for vcore. For more info the gyazo pics i linked have my cpuz and hwmonitor at both the normal and high temps.

 

[terry4536]

See the two links below.

I can't see the vcore in his screen shot. In the second link, the VID under "Intel Core i7-8700" is 1.348V . That is the max setting. The core speed is listed at 4419.32 MgHz . That would suggest that the OP has overclocked the processor.

I had a similiar issue, not with heat but with my screen going black when i'd return the computer from sleep - and it would never show the display - i'd have to do a hard reset. Never had a BSOD or any crash - i ran whocrashed and it showed the cause - at the bottom of the report there'll be a search link, and it took me to the exact solution

you might give it a try http://www.majorgeeks.com/files/details/whocrashed_free_home_edition.html

knowing what caused it to shutdown should give you a big clue

So the vcore in both of the picture is posted twice. Once in hwmonitor and once in CPU-Z. They are both roughly the same around 0.6-0.7vcore. If you still cant see the vcore on hwmonitor its listed under the voltages at the top of the screen shot.

I did a little research on overclocking a i7-8700k. Look in your BIOS for the "ASUS Multicore Enhancement". Apparently if it is set to auto, then it will automatically overclock all of the cores (with XMP). I would suggest disabling it and see if your temperatures go down.

Here is a discussion on this exact topic.
http://www.overclock.net/forum/297-general-processor-discussions/1639832-various-should-multicore-enhancement-default.html

 

[terry4536]

Here is a video on the Multicore Enhancement with XMP effect. This is specifically discussing the i7-8700K CPU installed on Asus motherboards. It also discusses that the VID will be max out. This is shown in the increased power use and increased thermal output. It points out with the Multicore Enhancement set to auto, a warning message is activated when XMP is used.

The video also points out that there is an increased instability with the Multicore Enhancement enabled. The Multicore Enhancement is enabled by default.

And here is yet another video on the same subject. Multicore Enhancement on Asus motherboards set to Auto (enabled) by default.
