If you're aiming to maintain that 13900KS performance, you might need to upgrade to another full AIO size. Otherwise, you'll have to lower the clock speed and voltage for the SOB CPU. Checking the test bench thermal data shows it handles much better than the Ryzen 7 5800X, which previously struggled with high temperatures. In my experience, this chip is powerful enough for content creation and video work, but it gets quite hot—so much so that users often feel uncomfortable. As someone who appreciates strong hardware, I find it pushing the limits a bit too far to own such a CPU without concern.
There could be a mounting problem and the 13900ks isn't really coolable by any aftermarket part unless you reduce the speed. Plus, you're using that basic ASUS board which draws a huge voltage from the CPU. Start with some lower voltages, observe the behavior, check the mount, see how clock speeds change, and if you need full performance, consider a better cooling system even the top Arctic Liquid Freezer II 420 can't handle.
He cranks the fans to 75%, isn't that too low? A mere 1450rpm, really... (and pump at full capacity?). I'd go the opposite way. Install a P12max and let it run! Edited July 22, 2023 by leclod
Pump running at full capacity is common among many users, especially for a 13900KW system aiming for optimal heat exchange. Fans operating at 75% capacity seem insufficient; you should aim for 100%. The nzxt fans are decent but not outstanding, and while they work reasonably well, they fall short in extreme conditions. A 100$ cooler is a solid investment if it meets the minimum airflow needs, though it won’t handle temperatures above 300W easily. Overall, it performs adequately but lacks the necessary power for such high heat loads.
All pumps in existence lose value without proper cooling—actually, they contribute heat. When cooling is present, you only need the pump operating at full capacity if you require maximum efficiency; otherwise, it becomes quite complex, but I’d aim for the point where returns drop significantly, likely around 50%. Maximum heat exchange doesn’t demand a pump running at 100%, just enough to move heat away from the CPU. Who am I to say, I’ve never used an AIO (still only 1450rpm, no wonder...)

It should happen if the hot air escapes from the top. But if the system is pulling in air instead of expelling it, it might be drawing in too much heat from the graphics card. What case are you using? If the side facing intake is a better choice, it would help keep fresh air flowing through the radiator.
