Listen, because there are a lot of different temperature threads here, and I still can't figure it out. AMD is new to me.

I have a 9800X3D with AIO BeQuiet Light Loop 360. Temperature in idle -> 50C. During load with Cinebench R23 -> 70C. In idle I have the pump at 2300RPM and radiator fans at about 800RPM. In load (over 75C) the pump is 2900RPM, AiO fans are about 2100RPM.

Here I mean the CPU Package temperature. Interestingly, in idle the cores are 35-36 degrees. However, under load the cores have the maximum temperature like the CPU Package.

Is this normal? In the Intel camp it was all more understandable.

Ryzen Master shows 54C in idle... HWInfo doesn't even see such value. I have the Curve Optimizer applied to -20. In load, Ryzen Master shows max 65C when HWinfo reaches 69C.
I reach similar temperatures in stability testing with Aida 64.

Testing OCCT in Extreme mode I reach 84C and doing performance tests in AIDA 64 in peaks i reach even 92C (for a second, only in peaks).

Are these temperatures correct? I have 25C in the room.

Of course there is no problems with performance or stability. The thing is that on the i9-9900KS (which was not among the cool ones) I had temperatures in idle below or close to 40C (also AiO 360 from BQ). And actually the cores of AMD are like that here too, but this high package "worries" me a bit. Can I trust the accuracy of these AMD CPU sensors?

Here are my exact specs:
▪︎ AMD Ryzen 7 9800X3D
▪︎ be quiet! Light Loop 360mm (top mounted, exhaust)
▪︎ MSI X870E Carbon WiFi

How is the AIO mounted in your chassis? One thing you can do on your build is to remove the front fascia and see if the temps change. If the temps drop then the intake to your case is being restricted.

Following that, you can use Ryzen Master to help undervolt your processor.
 
Its not an air flow issue.



AiO mounted on top, pump with 8mm offset. Its undervolted as I said earlier. But undervolt is only under load.
Temps under load looks ok in my opinion. I wonder why differences between CPU package and cores are so high (in idle 50C vs 36C). Many sources claims thats normal with AMD CPUs.

Oh my god, we have the same CPU, AIO cooler, and temps.
My idles are at 50C for the Tctl/Tdie and Die, but my core temps are at 26-27C.
During load, with a -20 CO I'm getting around 69C for Cinebench R23 and 64C for 2024.
OCCT Extreme temps are also at 85C.
I don't understand how the die and iod hotspot are almost 2x the temps of the cores with this cooler.
I'm using Arctic MX-6 thermal paste as well. My pump is running at 2,740 RPM, which seems to be the max, not 2900 RPM, and it's locked at that RPM as I can't really change it at all even with a fan curve.
I have 3 side intake fans, 1 rear exhaust, and the top-mounted CPU radiator fans as exhaust. (Basically negative pressure)

I am also curious as to why our CPU die/IOD hotspot temps are so much higher than our core temps during idle. Everything else seems fine under load. It's weird.

System Specifications:

Motherboard: Gigabyte X870E Aorus Elite WiFi-7
CPU: AMD Ryzen 7 9800X3D
GPU: Gigabyte Gaming OC RTX 5070 Ti 16GB
CPU Cooler: be quiet! Light Loop 360mm AIO Cooler
SSD: 2TB Samsung 990 Pro NVMe
PSU: Corsair RM1000x

What is the front fascia?
 
Your bottom fans are in wrong orientation.
Flip them around to intake orientation

And bottom fan in upright position is not needed at all. Get rid of it.

Think, how airflow is going.
If bottom fans provide air intake, then standing bottom fan immediately expels this air.
Air from bottom intakes can't cool anything if it gets immediately expelled.
Hey, you know how the hoses on your AIO pump tilt a bit upwards right? My hose connected to the pump is facing downward at the moment, did you do have to use any tools to get it facing more up like yours in the pic?
