Well thus far it seems my 97 degree temps with the 12900k were purely due to the extremes of Cinebench R23. I've read lots of reports of R23 generating crazy temps and not just with the 12900k.

Currently running Aida64 stress test with AVX and temps are in the 60's and low 70's with the D15S. Absolute max peak I saw was 77.

Will run Aida for 30 mins and then try another stress test.

Result:

4.9GHz

Temp: 60's to 70's

Voltage: 1.26

Watts: 177.5

Motherboard Temp: 21c.

Samsung SSD Temp: 39c.

Aida Bench Score: 116990. 7th place, with no overclocking.

Asus RealBench: Mid 70's to low 90's. 93c max temp. 🤣 Toasty.

 

Hopefully this will be useful to someone just setting out on the Alderlake journey.

My initial very high temps with Cinebench R23 (97 degrees) and RealBench were because I hit F1 on first boot and disabled Intel Power Limits. With Intel Power Limits now in place temps are much lower.

I ran numerous stress tests and then allowed Asus AIOC to do its thing.

Result: P-Core Target 5.4 GHz (single core). E-Core Target 4.1 GHz.

Temp in Cinebench R23 around 86C almost all of the time with very brief spikes to 92. Frequency limited itself to mostly 5 GHz but with spikes to 5.2 GHz. 

Score in Cinebench was 27369. Result without AIOC was 27015. 

Given the small boost in performance, I'm not sure if I will leave AIOC to do its thing or just stick to defaults plus XMP 1. 5.4 GHz is of course for single core loads which I doubt I'll ever experience. 

Tried boosting RAM to 5800 MHz from 5600 MHz and score dropped. 

My conclusion is very much in line with what Jayz2cents determined, overlooking Alderlake is a bit pointless. The gains in terms of frame rate in our applications just aren't worth it.

97 degrees was allowing Asus to ignore Intel Power limits and whack the juice in. With Intel limits in place and overclocking via AIOC (which over volts to a degree, mid 80's. I think that's rather good for an air cooler.

This is DDR5.

I've used Conductanaut when delidding but not between IHS and cooler. I use Kryonaut. I don't need liquid metal to be honest, I'm not desperate for the performance. And it is electrically conductive of course.

I'd be surprised if you weren't getting those temps with a custom loop and chiller. 

Don't need a chiller thanks.

I am completely sure you meant "overclocking Alderlake", but your wording did give me pause and a good laugh.  Intel now tweaks up stock performance such that overclocking gains are more of bragging rights than something of meaningful use (IMO it's been that way for its last few generations) and obviously Silicon Lottery got the message.  It seems recently that overclocking is more or less about being able to undervolt so the turbo freqs can be had on all cores.

BTW, congrats on your new build.  It'll be interesting to see how Win11 and software in general evolves towards fully exploiting the 12900k architecture.

Yep, they are pretty much overclocked CPU's right out of the box. Intel trying desperately to compete with AMD.

I'm sticking to W10 for now, until W11 is stable and reliable and all drivers updated.

Its actually looking rather lovely, the EvolvX and all internal components a nice gentle blue glow. 

Quite pleased with how the NH-D15S is handling it too. No temp issues. 

I'm waiting for my parts to arrive for a new 12900K build with a 3080 ti.  

Really looking forward to it!

Thanks for share you data. Once I get my system up and running I will be running all my test and will share the numbers. I also will be staying on Win 10. I can't be bothered with Win11 ATM. Better to run on a more stable environment were you know where you are rather than chasing a goal post they like to keep moving with one update after another. 😅

Yes exactly, my thought too. With a new system I like to run basic tests to ensure all is well. No sense adding another unnecessary variable.

Have you run any bandwidth and latency tests with your DDR5?  SiSoftware Sandra?

Cheers, Rob.

 

Who me Mr Freeze? 

 

If so no. Might do tomorrow if I'm feeling fruity.

Yes, Dr. Hot.

 

Do you mean hot because I'm sexy or hot because my CPU is warmer than yours? 

I'm sexy then.

I would not recommend using windows 10 for alder lake. As you know. These chips use the big little technology. Windows 11 specifically has thread director technology. Windows 10 only uses static level technology for such. I’ve personally seen benchmarks that show significant alder lake gains on 11 vs 10. 

Hi Mic -- I have also seen Youtubes that the difference in 11 vs 10 (even with the thread scheduler) is only 5-7%. I guess YMMV.
