I'd like to get mine a bit lower. I'm seeing temps around 44 at idle and 74-76 gaming. All stock except for xmp enabledI just built a partially new ststem, specs in sig. I have the Kraken Z73 on my i9 13900k, and in Desktop use it hovers between 28/30c to 35c/37, and in games like 45c / 54c in heavy gaming. Is that ok?
knock off some voltage, start with -0.025vI'd like to get mine a bit lower. I'm seeing temps around 44 at idle and 74-76 gaming. All stock except for xmp enabled
This is where my 13900K is usually at during gaming with a DeepCool LS720. Running at stock with XMP enabled. Others with higher temps may want to look at case airflow as well.I just built a partially new ststem, specs in sig.

With 24 cores in Cinebench it will fire up to 100 unless you have overkill cooling. What I do do since I only game is turn off most e-cores and disable hyperthreading. That way I can decrease the voltage significantly. Just yesterday I was able to pull off 32 degrees 150 W power and -0.100v. Somewhere between 12 or 16 core is more than enough for gaming if you ask me. If you do productivity work nevermind I would leave hyperthreading and all E-cores on. I don't so I can afford to turn them off.
What do you mean by efficiency? For example if you have 12 or 16 physical cores?Yah the problem is that hyperthread threads are used by thread director - you'll actually gain a bit of efficiency overall with it on
So..What do you mean by efficiency? For example if you have 12 or 16 physical cores?
...it continues onIntel classifies the performance levels on Alder Lake in the following order:
That means the system will load up one thread per P-core and all the E-cores before moving to the hyperthreads on the P-cores.
- One thread per core on P-cores
- Only thread on E-cores
- SMT threads on P-cores
Correct me if I'm wrong, but I believe this is for battery efficiency? On a desktop with 1300W power supply I don't think this would make a difference. Efficiency for battery power and eliminating unnecessary cores for gaming might be 2 separate cases to consider. Turning off cores that you don't need for gaming might save you power overall? My testing has proven this. But I am testing Cinebench which uses all cores. Basically each cores turned off translates into less power usage. I don't think you need more than 12 cores for gaming. 24 on the 13900 seems excessive?So..
My understanding of thread director comes from a number of sources, but the info is most easily understood from here: https://www.anandtech.com/show/16881/a-deep-dive-into-intels-alder-lake-microarchitectures/2
...it continues on
What this means is that without the SMT threads, it will mean firing up or keeping awake E cores (if the P cores are active and E cores are asleep, but SMT disabled) and/or reallocation to P cores as there is no demotion to SMT- therefore increasing power consumption - it is cheaper in terms of power to keep a P core awake and run two threads on it, rather than a P core and an E core.
I would think it'd need some sort of algorithm to go:
1. Profile thread on P core
2. If P core use of thread is low, move to e core, profile thread on ecore
3. if e core use of thread is low, and P core is active (for something else), move to SMT thread otherwise keep running on e core

Oh the irony.. 90C under full load is actually a good temperature.Get a buckle, it'll cut Temps 5C easy. I'd say a good temp at load is under 90C, lol.

I need to do some testing to see if 24 vs 12 cores makes a difference. I'll start with time spy extreme. Not sure, but I doubt many or if any games would use more than 12 or 16 cores max? The reason for turning off cores that games are not using is to get lower voltage along with higher clock speed keeping the max power draw lower which keeps the temperature lower. Less cores higher clocks. All just speculation though I would need to do a lot of testing.Now that I actually have time to reply properly..
Games and software aren’t coded for “cores” they are coded for threads. Threads can be time critical(Main game loop for example) or not time critical (sound loop for example).
If you have a processor core and you run a non time critical and a time critical thread on it at the same time, then your critical thread won’t be able to run at full speed.
This is where efficiency cores come in, you can run all your non time critical stuff on them and you won’t see a performance drop (at least that is the promise). The same goes for smt threads, your non-critical stuff can run on them.
As for turning off cores you don’t need for gaming, unless you’re a dev of the game you won’t know exactly how many cores you are using. Why not let the built in architecture of the machine and the OS control if cores are on or off with core parking and hardware duty cycling?

sounds like your mount might not have been good.Hottest core was 87C compared to instantly hitting 100C on all cores at PL3 with the 360 AIO

weird. pump on max? 'cause it shouldnt be doing that poorly...I mounted that bitch like 20 times lol, used a whole tube of paste on it. Tried with and without the aftermarket bracket too.

if youre happy with the air cooler, good. just odd for a 360.
475w!??! lol ok then, i guess it was doing ok, i just misunderstood.Oh no, it wasn't doing poorly, PL3 is like 475W limit. It was boosting to 5.8 with a ton of voltage. I just wanted to see what the difference would be if I dialed it back and air cooled it. I originally thought something was wrong but after doing some research its the expected behavior, as long as it hasn't hit 100C it will keep trying to add more sauce.

Can you please post all your bio setting changes you made to get those numbers please.So I did a little experiment, I swapped my 360 AIO for a Deepcool AK500 I have here, it is a supposed 250W air cooler. Quite a nice unit for the price I might add. I then set the motherboard to PL1 which is a 248w 300amp limit, and it actually does fantastic. I lose zero gaming performance, did drop about 3000 points on cb23 but I don't render anything so I don't care. Hottest core was 87C compared to instantly hitting 100C on all cores at PL3 with the 360 AIO. I ran a 10 minute throttle test before swapping to a single run to get a score.
