I just built my new PC and it was working great until I ran Tiny Tina's Wonderlands. While it was doing shader compilation, my core temperature shot up to around 95°C per core, which can't be normal, right? I made sure to remove the plastic from the bottom of the cooler and applied thermal paste like I always do, tightening all the screws properly. Is something wrong with my setup? Also, it seems like the Core Temp app is showing fluctuating values; now it's reporting some cores hitting 5600-6400 MHz. How is that even possible?

The reported temps might just be inaccurate readings. A lot of us recommend switching to other monitoring tools like HWMonitor or HWiNFO64. AMD has confirmed that hitting 95°C is typical for their 7000 series processors, so it should be similar for the 9000 series.
The 9800X3D can hit temperatures up to 95°C at max load, and that's actually by design. Even with good air coolers, like a Noctua D15, I see similar temps during intense tasks like Cinebench. For normal gaming, though, you should be seeing more like 50-60°C. If you're hitting those high temps only during shader compilation, it might just be how demanding that specific task is!
Yeah, shaders really push the CPU to the limits. I once had mine at 95°C too during a shader compile—but it ran fine in other scenarios.
I had the same issue until I undervolted my CPU, and now it maxes out around 75°C. Just be cautious when doing this for the first time; try to find a good tutorial so you don’t accidentally mess things up!
Thanks! I was worried that undervolting might be similar to overclocking, and I don’t want to ruin my setup.
Running at 95°C is definitely on the edge, and while the 9800X3D is built to handle it, you might want to check your case airflow. A room temperature of about 24-25°C can add to the heat, especially if your case only has basic cooling.
I keep my room the same temperature and can get close to that too, but my case has better airflow.
Honestly, those temps are pretty standard for the 9800X3D. If you're looking to get it under 90°C at full load, consider undervolting or upgrading to a larger AIO cooler. A decent 280mm or 360mm AIO could help a lot!
I felt the need to undervolt too with my 360 AIO; it really makes a difference!
I'll definitely try different software to confirm—thanks for that tip!
