12900k runs hot

[ir_cow]

First of all, he said 100C, not 90C. Secondly, 100C does not make perfect sense. I just ran R20 and the highest I saw was 79C momentarily.

I don't read well . 90-100c is R20 is still kinda normal, but 90c for gaming is not. You need to do more than 1 run to get that thermal soak going.

We have the same processor, but I am running an air cooler with a single fan at a low speed and he is running a triple fan 360mm AIO.

I also have my power limit "uncapped" as the EVGA Z690 Classified bios does not have a way to restrict power limit. My power limit as reported by HWiNFO64 is 4096W.

His temperatures should be much much better.

 

[sneekypeet]

They should be better, but MSI cheats the power states which runs the CPU at full tilt because as mentioned it sets 4096w as default.

I guess the next question is if these temps are spikes or the standard? AIO tend to have high spikes because the pump or fans don't spin up in time (not at 100% all the time), resulting is 100c before it falls back down.

When I run cinebench20 it throttles on 2 cores, 100° on core 4 and 7, the rest is from 95-97. I have now undervolted to 0.040mv and capped/underclocked the p-cores to 51-51-51-51-50-49-48-47 in intel xtu and now cinebench20 shows 80° and no throttling and 50-60 when gaming mw2.

Yes this is the way to go. This generation performs really efficiently when limited to 50x, the stock clocks 52+ are really a stretch.

Glad i found that out. It really doesn't hurt performance that much either.. -500 in cinebench20 score only.

 

[superjan]

Perhaps limit P1 and P2 to 125W as was tested here, on TechPowerup.

Where do i limit this? Someone who can tell me?

90+C is normal if you have the power state set to P1= 4096w

Is there something I can do about this?

 

[Deleted member 185158]

I'd just disable the E-cores and see if the thermals are better managed. It'll shave 50w right off the top.

 

[wanna_buy]

Can anyone with i9-12900K post stock Cinebench R15 and R20 scores with E-cores disabled? Please? I did not find anything online.

Disabling E-cores is a meme at this point. It isn't necessary to do.

I am interested how much P-cores score alone in Cinebench.

Change both the long term and short term power to 190 (by typing in the numbers when you have it highlighted like you show in your screen shot)

Then save and exit the BIOS.

We understand, two posts in short time. Make your own thread or buy one - you seem to run a lot of the old stuff.

When I do that in intel xtu and benchmark it i get power limit throttling? I test it in intel xtu first because it's easier to change before I do it in bios.

Hi,
Plenty of explanations here

Intel Core i9-12900K Alder Lake Tested at Power Limits between 50 W and 241 W

We test Intel's Core i9-12900K at various TDP levels all the way down to 50 W to determine how much efficiency is really in the new Alder Lake core, and how these power limits affect performance. Competing with the efficiency of AMD's Zen 3 Ryzen lineup is just two settings changes away. Show...

Yes, because that's what you're doing - limiting power to 190W.

Also, XTU will override what's set in BIOS, so it's best to use one or the other.

As Mr. Hi said above, take a look at the article he posted. It explains what performance to expect at different limits.

Tried now and the changes failed and pc turned off after 3 minutes and rebooted to bios.

I wouldn't power limit it at all instead I would just set the max clock to 50x for all core and try to get your load voltage at 1.25Vcore or below using offset/adaptive.

I thought why bother with starting a new thread when there are a lot of Alder Lake owners here. I didn't know it was so difficult to spend several minutes for changing a few settings in BIOS, restarting and running Cinebench tests.

Who knows, maybe in the future. Currently, I am satisfied with my 18-core Xeons and Ryzen 5900X.

 

[vMax65]

Something is not right.. One go into BIOS and set optimised defaults. Then reboot and go back into BIOS and set XMP 1. Test with Cinebench R23 muticore test with Hardwareinfo open to see what clocks your 12900K hits and what the highest temps are whilst running Cinebench. Also check what vcore hits whilst under Cinebench load.

Once you have done that and have a baseline. Also I bought the Thermaltake ILM bracket which did help but your temps for gaming are just way to high, so either the cooler is not on properly/not working or there is a setting issue. Also in Windows make sure you are on the balanced power plan.

Where do i limit this? Someone who can tell me (PL1 & PL2)?

You can set PL1 and PL2 (power levels) in BIOS.

I tried now to change pc case with better airflow, changed paste and mounted it together but same shit!!! Haven't mounted GPU yet, but this are the temps and Info from hwmonitor. And this is without doing nothing on core voltage offset, just lower all the cores to 50. I don't think it is the pump either, it respond when I change rpm.. i can hear it turns on the speed and the tubes are vibrating. If the pump had failed i would have gotten 100° straight away? It's 24° on idle.
