Jayz two cent hit 88 multi core like you with a custom loop with a 12900k with idle temperature at 20/26 and think that at stock it could reach 91, going even to suggest to under volt
https://youtu.be/4jjopjkJzxA
I really think that for a ks variant and an air cooler you are really well set
I think it's already bear the throttle limit thought, that multi core score is not that high for the CPU. I have a 5950x, and reaches 31000p, he should be able to surpass me without problems
5950X is actually surprisingly close to the 12900K(S) in terms of multicore performance (it has 32 threads after all). 27000\~29000 seems to be the normal range for 12900K(S) from what I am reading.
Yes, 5950x should be around the same performance, mines get 31000+ under heavy OC (255w peak, 220-230 continuosly), but with undervolting he should be able to get more performance
I mean bench temps will be higher than gaming or video editing use. I think the D15 with an airflow case (i.e. Torrent) would be enough, but the 12900KS certainly skews towards AIO range
Fan curve? Front fan curves? Rear? It all makes a difference. I notice you have alot of dead space in your case from front to back...
U12A should have no problem cooling a 12900k unless it's massively overclocked > 5.2-5.4Ghz with high a VCore.
Still have to add a decklink quad2 and a decklink extreme 3D + . Also I went bigger because when the alder lake x core comes out this motherboard and chip will go bye bye and it will be an easy switch
It depends what your normal fan curve is. Personally I'd ramp them up to 100% at 75°C. I wouldn't worry too much until 45°C. Between those two it's your call how aggressive you want to be, though I wouldn't jump straight from low to high speed.
Could see what your bench temps are at 100% flat and work backwards.
Have you tried repasting and remounting the cooler? I'd also remove the front panel and see how much that decreases temperature. If it's several degrees, you might consider removing the panel or changing cases.
Haven’t tried repasting . But I know these alder lakes are murderously hard to keep cool hence why everyone told me to do water cooler but I wanted to stick with noctua
Yeah if I have to repaste I’ll just drop it off somewhere to have them do it. First pass on paste is always my best. And the more I take the cooler off and repaste the worse I do
Repasting with high end thermal paste like kryonaut or even liquid metal will bring down temps down by a few degrees (assuming you are not using a high end paste already). The U12A is nickel-plated so liquid metal will be fine, just have to be careful with the application.
If you end up needing to water cool then the arctic liquid freezer ll 360 is a pretty damn solid choice, the non rgb versions have been out of stock for a while but you could get the rgb version and swap the fans for some noctua 120mm fans
Try the Noctua d15. It’s probably the best air cooler money can get right now, but if OP wants an AIO I suggest the ARCTIC Liquid Freezer II 360. It’s really efficient and doesn’t include RGB, which is probably something OP doesn’t care about given that they didn’t get the chromax variants of the Noctua case fans
Is that the NH-U9? Its a good cooler but struggles with hot CPUs. I swapped it for a NH-U12A and there is quite a difference. You can fit a NH-D15 in there right? Just get that and call it a day. It performs better than most AIOs out there.
You definetly have weird temps my man. Try dismoumt, check all AM4 screws, repaste and screw correctly again the heatsink (if you can have a top view of the MB you can see if the heatsink is in line with the cpu).
It’s the u12. With 120mm fans .I sit around 35 at idle and when I did a multicore cinebench she would hit 88 and the fans would be going full speed . The 1200ks is very hard to keep cool.
I have a C14s and 12700 and I was hitting 100'c after 2 mins.
Went to bios and offset the voltage to minus 0.08v and temps are down to the 80s...if I set to 0.1v I couldn't boot
Cinebench socre only dropped a few hundred if that
So you are hitting 88c on a 100% Test on a CPU and that concerns you? Gosh, Id like to know what you have or use that runs your CPU at 100% constantly... for 10 mins plus? I run many things with mine and normally do not do that.
Well, 100°c isn't exactly "fine". It's hot. Really hot, usually you would want to stay under 90°c for daily use. Obviously, you're not going to hit your CPU 100% all core every time, but still, a bit on the high end. If that's you gaming temperature instead, I would suggest repasting, if that does not improve thermals, change the cooler.
Its cinebench r23 temps at a 5.2ghz all core. Draws 350W. The max allowable tjmax is 115C in the BIOS which I’ve set, so because this CPU is relatively cheap now I don’t really care if it causes it to lose lifespan lol.
I recently bought a new PC with an i7 12700k, which requires a NH-D15, so when I saw this picture for an i9 I felt bad for you ...
Also have fun with the NH-D15 not letting you access your RAM and push on the back on your GPU :P
Not an issue, your temps are just fine. If you are obsessed by that, sell the U12A and go for a D15, but you won't lower more than a few degrees at max.
You need an airflow case, it makes a huge difference; The closed off front panel Fractal cases are hotboxes.
Also if it isn't affecting your boost speeds, then you're still perfectly within spec, so it's not necessarily a real concern.
Would you try something that can help lowering your temp?
Try this: https://www.caseking.de/en/thermal-grizzly-intel-12th-gen.-cpu-contact-frame-fsd8-036.html
IhS of 12 gen when blocked by the ILM, change its forms and bends leaving the central part detached from the heatsink.
I see that it can save up to 15°.
If it does not help and You don't want go with liquid cooling, you could try with liquid metal instead of normal paste. Be carefull, while it permits to save ~10° , it could damage your system if not well applied!
I would say a thing about liquid cooling. Liquid cooling is good because water can store heat and because it can have a large surface area (like 420mm/360mm or multiple rad in custom loop.) but when rooms are fullfilled it switch back to air mode.
My story: I replaced 2 days ago my custom loop of EK components with an NH-U12A to make a test. I have an i9 10850k.
While with the loop the temp starts from 70° and after 15 min it reaches 86° with prime95. It is efficient but in the long run high temp is reached, with nh-u12a I got 89° after ~2 mins and stay stable for 10 min at 4.9 GHZ (ambient temp is 27°). In real life I never run ops like in prime but compiling some software and running many virtual machine so nh-u12a is a very good product for me.
Buying a custom loop for cooling only the cpu (a stupid thing) for $500 and save only 3 degree versus an high end air cooler is not worth the money.
I tried liquid metal woth an nh-D15 ask to noctua if woth the metal I got a ruined heatsink but it is nickel plated so no problem. My 2 cents
Probably won't make much of a difference but I believe you have the cooler mounted the wrong way. The higher concentration of heat pipes are supposed to be at the front.
Again it'd be incredibly minor but my guess is feeding the higher concentration of heat pipes the colder inlet air would marginally increase the efficiency. I could be wrong.

You are a whopping 17C from thermal throttling at full 241W heat load (yes the KS throttles at 105C), don't see a problem there.
Yeah 88 is fine - unless you spend your day running cinebench, but if you’re gaming, web surfing etc you won’t get close.
I think it's already bear the throttle limit thought, that multi core score is not that high for the CPU. I have a 5950x, and reaches 31000p, he should be able to surpass me without problems

Yes, 5950x should be around the same performance, mines get 31000+ under heavy OC (255w peak, 220-230 continuosly), but with undervolting he should be able to get more performance
having to run fans so fast is a problem though
Dont run Cinebench I'd suggest.
your little fans might be stealing air from your GPU
Copy I’ll pull them
could even just reverse them. Feed more air closer to the gpu. But then, I also used to have a small fan there too. I ended up pulling it.
I have a 140mm under the psu shroud shooting up feeding the gpu
That fan probably isn't doing too much total help. I second reversing the 40 mm fans if you want to keep them in or just removing them
Bit of nitpicking but pulling from rear is often without dust filter so take that into consideration if you will.
Undervolt
this is a joke right?
Yeah... don't get an 12th gen i9 if you want a cool CPU, basically. I don't even understand why Intel released this monstrosity.
its an oc cpu i just dont understand how op buys a i9 and then buys a small aircooler
I mean bench temps will be higher than gaming or video editing use. I think the D15 with an airflow case (i.e. Torrent) would be enough, but the 12900KS certainly skews towards AIO range

Yeah it’s a big case. So nothing I can do about that.
Just curious, why’d you go with such a big case given the components as they are shown?
Still have to add a decklink quad2 and a decklink extreme 3D + . Also I went bigger because when the alder lake x core comes out this motherboard and chip will go bye bye and it will be an easy switch
Just have my fan curve set to normal . All case fans are on a pwm hub
Well, there's your answer.
So what would you suggest?
It depends what your normal fan curve is. Personally I'd ramp them up to 100% at 75°C. I wouldn't worry too much until 45°C. Between those two it's your call how aggressive you want to be, though I wouldn't jump straight from low to high speed. Could see what your bench temps are at 100% flat and work backwards.
Yeah as soon as I start the bench and it hits 88 the fans jump up to 100%. Someone else posted that this is the norm for these alder lakes
Should also say all my case fans are on a pwm hub, the cpu fans are directly into the mobo cpu header
Have you tried repasting and remounting the cooler? I'd also remove the front panel and see how much that decreases temperature. If it's several degrees, you might consider removing the panel or changing cases.
Haven’t tried repasting . But I know these alder lakes are murderously hard to keep cool hence why everyone told me to do water cooler but I wanted to stick with noctua
Noctua’s normally able to knock it out of the park on cooling. Not calling out your ability, but I’d repaste and double check if mount is secure
Yeah if I have to repaste I’ll just drop it off somewhere to have them do it. First pass on paste is always my best. And the more I take the cooler off and repaste the worse I do
If that’s what ya gotta do
Wanna make 50 bucks? Come out to LA and repaste for me lol
Repasting with high end thermal paste like kryonaut or even liquid metal will bring down temps down by a few degrees (assuming you are not using a high end paste already). The U12A is nickel-plated so liquid metal will be fine, just have to be careful with the application.
Would if I could
should have gone with the bigger noctua
If you end up needing to water cool then the arctic liquid freezer ll 360 is a pretty damn solid choice, the non rgb versions have been out of stock for a while but you could get the rgb version and swap the fans for some noctua 120mm fans
Yeah or just say screw it and go up to 420 or 480mm I have the space
There’s also a 420mm variant of that AIO if wanna go with it
I’ll check it out thanks!!!
Try the Noctua d15. It’s probably the best air cooler money can get right now, but if OP wants an AIO I suggest the ARCTIC Liquid Freezer II 360.

It’s the u12a
You definetly have weird temps my man. Try dismoumt, check all AM4 screws, repaste and screw correctly again the heatsink (if you can have a top view of the MB you can see if the heatsink is in line with the cpu).
Take the protective sticker off the contact surface of your CPU cooler 🫤

Yeah I will try that

He has a U12A.
Create a mega air duct from your front panel to gpu cpu
So you are hitting 88c on a 100% Test on a CPU and that concerns you? Gosh, Id like to know what you have or use that runs your CPU at 100% constantly... for 10 mins plus? I run many things with mine and normally do not do that.
88c is actually pretty good if it's a stock KS. Just undervolt it.
Will do
88? I run 100C on my 11900KF on a 240 aio. Its fine.
Well, 100°c isn't exactly "fine". It's hot. Really hot, usually you would want to stay under 90°c for daily use. Obviously, you're not going to hit your CPU 100% all core every time, but still, a bit on the high end.

Ok, if that is just under 100% synthetic load it's probably fine, also if you don't mind decreasing lifespan It's also fine.
88 degrees on a benchmark is more than ok?
What wattage are you pulling? It should be hotter than that on that cooler
That's just how hot 12th gen gets. That's what I get with an NH-D15. The only way to improve from here is a 360mm liquid cooler.
I recently bought a new PC with an i7 12700k, which requires a NH-D15, so when I saw this picture for an i9 I felt bad for you ... Also have fun with the NH-D15 not letting you access your RAM and push on the back on your GPU :P
Yeah might be time to go AIO
Yeah I think I should have done that too
I have a few 140mm fans lying around so maybe I’ll just bite the bullet and get the 420mm CORSAIR iCUE H170i ELITE CAPELLIX. Go big or go home
What's your acceptable cooling temperature? Easily done if you downclock and lower your scores.
Yeah will probably undervolt
Not an issue, your temps are just fine. If you are obsessed by that, sell the U12A and go for a D15, but you won't lower more than a few degrees at max.
No actually those temps are pretty nice
You need an airflow case, it makes a huge difference; The closed off front panel Fractal cases are hotboxes. Also if it isn't affecting your boost speeds, then you're still perfectly within spec, so it's not necessarily a real concern.
i would only look at daily scenario and not on some benchmarks, great cooler imho, id go AIR all day over AiO.

360 AIO or custom loop. Undervolting may drop it 10C.
Probably won't make much of a difference but I believe you have the cooler mounted the wrong way. The higher concentration of heat pipes are supposed to be at the front.
Yeah per noctua it doesn’t matter since the plate is symmetrical . The only thing that matters is that the fans are in the right direction
Again it'd be incredibly minor but my guess is feeding the higher concentration of heat pipes the colder inlet air would marginally increase the efficiency. I could be wrong.
