Now that I think I hit the limit of with undervolting it's better (doing it per core, it took me 2 weeks or so): around 60W on windows with most everything closed. 50-55 degrees celsius or so temperature (360mm arctic freezer pro iii AIO), current case has no more than decently good airflow

Thx for letting me know! It must be some setting in windows or the mobo I was playing with when undervolting, it hasn't crashed in a while so I'll revisit them
Hi! First time posting in this thread, I’m looking to see if anyone has managed to solve a situation similar to mine.
My 9950X3D runs very hot, 60 and 70°C at idle and while it rarely spikes during gaming (usually tops at 70°C, some games 75), it goes all the way up to 95°C in benchmarks and stress tests.
I've been struggling with this for a few months now. I have a NZXT Kraken Elite 360 v2, which I’ve had replaced twice, so I’ve actually tested three units. All of them were noisy and, most importantly, performed poorly when it came to cooling. Given the noise and NZXT’s declining QC reputation for this AIO model, I switched to a Lian Li Hydroshift II, but same result, it gets loud above 50% fan speed, and the temps are exactly the same.
I’m using a MSI X870E Edge Ti, and I highly doubt the motherboard is the issue. Everything was stock at first, but then I disabled PBO and adjusted some other settings, no change at all. Whatever I do, the temps just stay the same, unless I manually set a thermal limit, for example 80°C, of course.
I’ve re-pasted, reseated the pump, double-checked airflow (which is excellent), and even got a CPU replacement from AMD, still no improvement. I'm starting to wonder if the motherboard is involved and if there’s something in the BIOS I overlooked?
I’m considering trying an Arctic Liquid Freezer III next, just to see if even a well-regarded AIO gives me the same bad results, but before that, I wanted to ask, has anyone with similar temperature issues actually managed to fix it or significantly bring them down?

What are you using to monitor the temps and is it fully up to date?
Have you checked the temps in the bios to see what it says in there?
When installing the CPU cooler did you go round in a circle or did you tighten them a little each time from opposite sides?
Your current cooler should be fine, I do not think you will see any difference going to a Arctic Liquid Freezer III
This all seems very strange mate, sorry to hear. No similar reports out there with this same mobo? BIOS up to date? Any chance you could try it with another one, perhaps some mate's? I'm not super familiar with MSI but maybe if you show us exactly what you have changed from stock (even though such temps at stock are also strange)
I bet some blood sweat and tears have gone into this8300C34 stable, low VDD 1.65v 1.45v VDDQ, 1.135v SOC (actual is 1.125v), 1.446v VDDIO, 1.128 VDDP.
New improved Karhu output from 8200C34 (369.42MBs) to 8300C34 (371.01Mbs).
I will improve on that output with subtle voltage tweaks and probably end up around or just under 372 MBs.
Im using and have used the NZXT 360
AIO for years now and am idling at 40-45 degrees and low 60’s while gaming.
Are you using NZXT Cam? If so do you have the pump and fans set to “CPU Temp”? Some people have it set to “liquid Temp” which will mean your fans and pump will change based on that temp instead of the actual CPU temp.
Hwmonitor, Hwinfo, L-Connect and NZXT CAM
The BIOS almost always shows between 60 and 63°C when I’m in it, which was actually the first thing I noticed on this PC, the BIOS temperature seemed abnormally high. The motherboard sits around 50 to 55°C for example, and the GPU has no overheating issues at all.
I used the cross method for mounting, tightening top right then bottom left, etc. On some AIOs I tried tightening as much as possible, on others I left it a bit looser, but nothing changed. No matter what I do, I keep getting the same temperatures D:
The CCD temps are fine, but it's the package that hit really high temps
Unfortunately, I don’t have another motherboard on hand. The only thing I could potentially do is take the CPU to a shop and test it in a different build to check the temperatures. If the results are similar, I could reasonably assume the issue lies with the CPU ,
but as mentioned, this is already a replacement unit. Having two in a row with thermal issues would be extremely unlucky.
The V2 version or the older one? At what percentage do you run it in CAM?
I do use CAM as well, but nothing changes even when I tweak the curve. I originally thought NZXT was the problem, but I’m having the exact same issue with a Hydroshift II

@LtMatt
Timings inspired by yours, seems to need a lot of VDDQ for some reason, maybe because its a 48gb kit though, any less and I get early errors in TM5 1usmus profile.
I brought a new 9950X3D, sorry OCuk not from you but from a store in Bolton, the one I received from OCuk was the biggest pile of poo id ever stepped in, this one is performing much better.
I tested it in my Mrs ASUS B850 Strix ITX board first which detected it as SP121, in my X670E Gene its detected as SP119.

Looking good for M Die.@LtMatt

Pretty happy with the results, just testing to do and then i'll start playing with the curves (the CPUs not the Mrs)

Is this the CL26 48gb 2 dimm kit? Nice results!

no, this one: https://www.gskill.com/product/165/374/1697008897/F5-8400J4052G24GX2-TZ5RK
I do want to try one of the 6000 CL26 kits though, see if I can push it to 6400 CL26 or even 6600 CL28 which would be a great sweet spot with 2200 FCLK.

The V2. Try at 100% and see if that makes a difference. Set it to CPU and not liquid temp.
In the bios are the pump and fans showing? You could try adjusting them this way. Just set them to 100% to start with, then if temps normalise you can change them later.
Very odd that changes in CAM are not taking affect. Are you sure it’s all connected properly?

When I change something on the NZXT curves, it only affects the pump noise, starting from 50%, it gets really loud. All three units I had had this issue, and I ordered them all from Amazon, so I’m not sure if that’s related. Can I ask where you got yours? It doesn’t seem to have the same problem.
Even if I set it to CPU or liquid temperature, the temps stay the same too.
I bought mine from Bolton. I’ve bought previous models from elsewhere over the years. I really don’t think it’s the cooler though. All 360 AIO’s will perform pretty much the same and I highly doubt you’ve been unlucky enough to have 3 defective units.
Did you check the bios fan and pump settings?
Yes, the fans run at 800/1000 RPM or a bit more depending on the temperature, and I’ve tried the pump in both PWM and DC mode, the noise doesn’t go away and doesn’t change with temperature either.
After trying several pumps, I’m starting to doubt that the issue comes from there. I’m now suspecting the CPU or the motherboard.
How do you have your radiator installed? You could try repositioning it and see if that helps.
