Just adding that I am using the latest bios from asus, 811. Thanks.

 

Need to see more info like voltage/vcore and CPU Power. Example

Edit and prime95 yeah even watercooling probably wont cool it. Depends how the bios setting things.

 

Weird how mine shows current voltages at 0.84V??

You have a bunch of readout hidden or cut off. I have no idea what is going on from that.

Look at my screen shot you need to look at Vcore and CPU Package Power

 

That looks like insufficient cooler, bad cooler mounting, or paste issue. to me.
Otherwise bios is janked. have you reset the bios to default?
And also running the latest bios.

Forgot to mention when setting XMP profile double check you CPU settings as it might overclock or overvolt automatically,
reset_CMOS and don't use XMP, test it out.

Yeah, I'm getting about the same with the Dark Rock Pro 4. I'd expect a little better performance from the D15, but that looks about right.

Chip runs hot.

 

Should I tweak load line a bit more to allow for more vdroop, would that drop the temps a bit ? It seems to be stable at level 4, and 1.34 vcore. at 1.33 it crashed under load. My goal is to not have throttling ... I don't care about overclocking this one, it's fast as is

 

Gonna need

You need to set per core OC. or and set a wattage/temp limit. There are different ways of doing the same goal in the end.

You are only going to be able to cool probably 1.2v or less under load is my guess. Not sure as I havent used air cooler on 12900k so you need to find what that is like a 46 or 48 or less all core.

Prime95 is super stressful and most dont use it that I know of. I think more people use something like Cinebench r 20 and r23 to stress test. They are more realistic stress tests.

 

I suppose I could use an upgrade of my 10+ y.o. case now (no space for the water cooler)... what is the best plug and play water cooler I can buy for these chips? Which outperforms the Noctua D15 by a good degree?

Thanks

 

Arctic 420 is one of the best for cooling and lower noise levels. That is what I am using and I also have a custom loop and compared temps and they are identical. It is tough to find a case the fit the 420 though. I went with Fractal Torrent.

12700k + ROG STRIX Z690-A GAMING WIFI D4... Read some of my posts in that thread for more info if you want.

This vid show the diferrence between 360 vs 420. 9c on 12700k. It is a pretty jump up in cooling if you can fit it. 360mm wouldnt cool 12900k in that vid.

 

try to do the washer mod, someone else with a d15 got 30c lower temps because the socket clamp bent the ihs too much. the contact to the cooler was really bad

 

Even with the Noctua socket 1700 adapter (officially released for this) ?

 

The NH-D15 isn't rated for the 250W+ your CPU can output.

Yes, it is. It even has "best turbo/overclocking headroom".

In fact, props to Noctua for acknowledging that "TDP" alone is becoming kind of meaningless.

Because the Dark Rock Pro 4 straight up advertises 250 TDP even though everybody knows that it's smaller than the D15.

Don't go around telling anybody that the largest air cooler on the market can't handle the 12900K.

 

Stop chasing prime95 stability. Set settings and just use your PC as you intend to use it instead. If you get errors or crashes, increase the voltage. In a few months you'll have a stable PC.

 

Hi,
Thanks for feedback. I am a perfectionist, so if I have stability in prim95, I know it is stable in everything I throw at it

. But it is not unstable, it just has 3 out of 5 performance cores throttling down due to hitting the max temp. It is still stable..
I suppose you are right, no point throwing prime at it. I see in games it is quite allright. The max usage it gets is games and photo editing in photoshop, but that is also piece of cake for this processor. Fans barely spin up when I edit.

 

Jesus! You guys here are more heated up in your beliefs than car guys..... all good , peace all.

 

For the price that it drops to every now and then I’d say the arctic cooling liquid freezer II 420 is hard to beat.

 

Adding screenshot of AC420 on 12900k @312w no way nhd15 will cool this

 

How loud is it compared to a Noctua cooler at idle ? I don't care when I do gaming/editing , it can spin up, as the video card is way noisier..

 

I found it at Amazon for 125, I am buying it. Now the hunt for a new case begins...

 

Maybe over played/hyped but still useful info.

Adding this for people new to AIOs

So you can remove the front 2 fans and stick the AIO cooler there ?

 

Yep. It is a tight fit but it can be done. Someone else on this board did it and he is using push/pull. I think the default setup is fine. I just put the fans in pull as push will be harder to setup(line up fans and attach rad.. You will see when you get it. But push can work also.

You have to remove bottom front 140mm as tubes will hit the fan. You can see it in my pic.

 

@bscool Thanks for all your help! all coming together today... man that case is big

 

Hey, @bscool one more quick question; where do I connect that little 3 pin dongle that comes from that led light strip under the power supply to light it up.... I can't seem to find an appropriate connector for RGB or lighting on motherboard.. I have an Asus ROG Strix z490-e wifi... many thanks!

Otherwise it seems to be running under 90 degrees now with full prime 95 load, with not much more noise than the noctua Nh-d15, which is nice... and that's on the 2 hottest performance cores, others are under 80...

 

Nevermind, I found it.. just a pain to connect. I found an RGB connector at the top of the motherboard, after looking in the manual RTFM.
