The O11 mini is a great case, do it! I use a Fractal North and have a huge air cooler.

Yep fully agree with PDifolco above, don't overpay for motherboard and cpu. Sure 13900k is nice but in real world day to day, a 13600/700k is exactly the same. You can even tune the 6000 CL32 memory down to CL30 and gain a little extra performance for 0 cost.

Repaste and refit cooler, double check fan speeds. That said, the 5800X3D is supposed to run a bit hotter than the 5800X despite drawing less power due to the 3D cache design. For both CPUs, AMD said they are safe up to 90C. These CPUs are smart, if you hit 90C they will try their absolute best to still maintain their turbo speed without activating the throttle button. Those temps are generally observed under benchmarking though, NFS Heat is not a CPU-intensive game generally but who knows...

The 13900K does not thermal throttle under any normal circumstances. Running CB23 is not considered a normal use case. And even so, it can run 95-100C while still maintaining 5.5 all (p) core. Not to mention pairing with actual high speed memory, which AMD will most likely take 1-2 more generations to reach, ect.. Not trying to sway your opinion, just make sure you consider all options carefully as its' a big outleigh especially if you don't upgrade often. On another point, after reading your OP you appear to believe these engineers are "morons" for designing it this way. Well, have a watch of this and see how you feel:

No stick to 3600. Lower the CAS the better. There is also IMC silicone lottery to consider, most chips wont run 4000 with 1:1 Infinity fabric to match.

If you want to avoid MSI then just go with ROG CROSSHAIR X670E Hero and you ll be happy. Good board with good feature set and no doubt will have bios updates to support new gen cpus as they release.

If you take 4 months to notice such amount of money "missing", then it's on you. Google is at fault perhaps, but the dude is a tool sorry.

I run 4000 CL15 on a 12th gen cpu fine, however this is largely the upper limit (some very lucky silicon people can do 4200-4400, but not many). I am unsure how 13th gen scales with ddr4 but I have doubts it will run that speed. Also don't worry about voltage, my kit runs at 1.5v daily and has been for months, it's not a problem. Just have a well ventilated case so sticks don't go above 50C.

Looks good to me man, although I'd personally go AIO instead of the tower cooler, 360mm at least as well given how how these chips run. Rest of the config is spot on for your usecase.

My suggestion was based on his requirements, not my own. OP mentioned he had no clear budget in sight and that he wanted to not touch anything for 2-4 years. I upgrade to the latest and greatest because I can. Maybe one day you could too Peace

If you want futureproof, 13900k and 4090 is the way to go. It's what im swapping to as soon as they are out, especially for 4K RTX gaming at max settings.

I personally cannot wait for this, power consumption and heat do not faze me at all (and anyone buying a top tier enthusiast product wouldn't either), so it would be cool to see if 6ghz all P core is possible with custom cooling. For 13th gen 4000 series build I think I shall get a MORA 420 Pro as 360mm AIOs wont cut it lol.

Perhaps reach out to them and ask if they can make you one? It won't be cheap but then again, no build in that case would be.

no

Also make sure you undervolt that CPU and optimise memory timings. Even on a 360mm rad, stock bios settings push 12th gen chips in 100C territory when running the likes of CB23, OCCT ect. Happy to help you with that via DM if you prefer down the line.
