i7 13700k thermal throttling

[Psyshox]

I had a new pc built from a pc shop and upon testing I found out that my i7 13700k was thermal throttling.It hits 100C on any stress test(Cinebench,AIDA64) and downclocks to 4.1-4.3ghz.I have a

MSI Z790 Tomahawk DDR5 Motherboard with Deepcool LS 720 AIO.I only have one 8 pin cpu cable connected to the cpu.The additional 8pin cpu cable is missing.Would that lead to performance loss?My cinebench score was 25000 with the cpu running at 100c for 10mins.I tried undervolting,changing lite load,PL1,PL2 and nothing seems to fix the overheating problem.I also noticed my power usage only being at 120-140W.Ive seen videos of it drawing 200+.Is my aio (Deepcool LS720)not properly working?Radiator mounted on front.Case is coolermaster td500 mesh with front fans as intakes and top outtakes.Please help.

No, the additional cable isn't needed unless you're doing some very aggressive overclocking of that chip.

Do you know what the score and temp is after 1 loop rather than a 10 minute thermal test? That would help diagnose if it's a cooler issue or some sort of BIOS setup issue.

Yeah, that shouldn't be that low, my personal 13700K at stock settings (MSI Z690 Unify-X, so unlocked power limits by default) will draw almost 300W in a single loop of R23. It sounds like its thermal throttling pretty hard, but it could be that some of the power limit settings are misconfigured.

It was one loop bro not stability test.Temps go down as soon as I stop the test.On idle temps are around 45-55C mostly staying at 50+.When playing games even at %usage huge spikes like from 65-78C at 15% usage.Should I reset bios?Do you think it could be an issue with the aio

First off, make sure to quote so we get a notification. I just happened to still be on the page and saw it.

That's way too hot for a 13700K at idle, it should be more in the low 30C mark rather than the 50C mark, at least if mine is anything to go by (granted I'm on a custom loop with a contact frame, so about as good cooling as you can get, but still).

Not a bad idea, I have my doubts on how effective it would be but it at least can't hurt.

It really sounds like it, a 360mm AIO shouldn't be that bad. I'd remount it first, see if the thermal paste application is terrible or something like that, but it really sounds like the AIO is getting gummed up somehow so getting it replaced is probably your best bet.

Maybe the label (sticker) is still on the AIO?

Those are not idle temps unless you're closing any apps that are running.

Temps going up and down with usage are normal. 

What rpm are the pump and cooler fans at?

Mines the exact same on my 13700k, just installed my cpu yesterday and with a 360 aio on a thermal right contact frame, I idle around high 40’s. My first Cinebench r23 run was 26k 3 P cores hit 100c thermal throttling, the rest were around 95c. I reset  the thermal paste twice (thermal grizzly). Only by setting the power limit to 253 am I able to stay under 99c in r23 multi core run with a score of 27500. Any ideas?

Update, undervolted core voltage -0.090 power limit 288 pl1/2 and not going over 98c R23 score 29k. At 253w power limit it didn’t go over 94c but r23 score was 28000.

my cpu aio pump was faulty got a new corsair 360mm aio and now c23 score is 29.4.I cant get it over 24.5 no matter what i do.

I'm using a Dark Rock Pro 4 and getting 38c at idle. With undervolting, my 13700k doesn't go past 87c.

Did you use XTU to undervolt?
My 13700k is reaching 100c on several games.. I tried installing XTU but it won't start even after I updated bios to the latest version.
I'm a noob at BIOS and don't know what settings to change manually.

I'm having the same issue. (https://pcpartpicker.com/b/Kg3Zxr)

Idles at ~50C and thermal throttles while stress testing with Cinebench R23.

Disabling turbo boost "fixes" the issue at a cost of a huge performance loss.

I suspect it has something to do with the BIOS settings.

 

Couple of weeks later I built a very similar system with the same 13700k and temps were ~15C lower with a different motherboard.

Second system (https://pcpartpicker.com/b/QFPV3C)

 

Too many pips experience thermal issues with these 13700k chips.

Doubt it a hardware fault given the volumes.

I have concluded that the LGA1700 package that Intel uses for the 13th gen Core processors has insufficient thermal conductivity.  In other words, the problem is getting heat from the die, through the lid of the package and into the cold plate of your AIO cooler.  I believe this because die temperatures rise instantaneously to the throttle limit at 100C even though the water in the AOI is still cool.

 

In my case I am running an Arctic Freezer II 240 on an Intel i7 13700K.  I hit 100C within seconds when running the CPUID Powermax stress test, AVX mode.  The only thing that helps is under-volting.  The Intel Extreme Tuning tool is great for trial and error analysis to see what is stable.  Then I set the under-volt in the BIOS of my ASRock motherboard.  I run -70 mV.  That results in a few degree reduction in temperature but I still hit 100C, just less often.

 

In defense of Intel, these stress testers operate the processors in a way that is almost never seen in actual computing. The only real-life application that I know to throttle is building the Linux kernel. That process runs as many simultaneous jobs as you have cores in your chip.

Just completed cinebench r23 multi core test with highest temp beeing 89°C with the asus rog strix LCII 360, thermal grizzly contact frame in a Phanteks G500A case
so 6x fans spinning up at a Temperature curve idle temps are around 29-35C depending if i'm running ultraquiet mode or not

score: 28512(everything stock)

next will be buying the themal grizzly Crysheet as i just went with using the paste that was already on the block from asus

A lot of the comments on here stem from people not fully grasping that most of the higher end Intel processors pull 300w or more and how you need a pretty good cooling solution to dissipate that heat or to undervolt. Even the 13600k will draw 280w or more with just a mild overclock if you don’t drop the voltage.
