Hello, I understand this has been talked about before, but it still feels strange. I recently purchased the 5800X3D and set it up with a small tower cooler (pure rock 2 FX, 150W TDP). It began overheating right away during Cinebench and then kept rising to 80-87°C in games. After a remount, the issue persisted. I’m using TG Kryonaut and manually spreading the heat across the CPU. That’s why I decided to buy an AIO cooler for a while, and I went with the "Corsair H100i RGB PRO XT." It’s the biggest one I could fit in my case. While it performs better in games, it’s about 10-15°C cooler, but it still reaches 80°C quickly in R23 and then slowly climbs to 90-91°C before throttling. The radiator is positioned at the top of the case, drawing in fresh air without expelling hot air. I’ve heard that high-end CPUs can get hot due to the 3D cache between cores and the IHS, but is that typical? It’s not harmful technically, but it’s not the best setup. Anyone have any advice or insights? Thanks, lambo603

Your airflow might not be sufficient for the amount of hot air in your situation. Even though the radiator draws in air, there should still be room for it to exit properly. You may need a more efficient computer case to improve air circulation.

Keep it simple—those fans are set up correctly for airflow. The front units handle intake, while the rear fan manages exhaust. Since water temps stay under 35°C during gaming, it suggests the cooling system is working well. The issue likely lies in heat transfer efficiency from the CPU to the AIO, not the fans themselves. Unless you notice unusual noises or leaks, these temperatures are probably normal for a 3D setup.

That's typical behavior. Adjusting the temperature by changing the CO offset is effective. Many users recommend around -30, though consistency varies across processors. On my system I settle between -22 and -23, which cuts heat by about 11°C and lowers it further to ~15°C at -30. For benchmarking, I’m only stable near -30 offset. CO (Curve Optimizer) adjustment should appear in the BIOS under PBO settings, shifting the voltage/frequency curve to maintain consistent timing at lower voltages. The adjustment won’t drop below -30 even if you try to set it lower.

I'll give it a shot, just plug in -20 and see.

It seems the desired action isn't available in your BIOS settings. Are you looking for alternative methods to achieve this?

Do you possess the latest BIOS? Many systems should already include it in updated firmware, yet if missing you can still achieve it the traditional method... which I find overly complicated compared to simply adjusting a setting in BIOS and finishing.

Yes, I'm confident about that. Asrock only introduced this feature with the Agesa 1.2.0.8 update, and my board is still running 1.2.0.7 according to the latest bios. I’d rather avoid using that software since it’s simple to cause issues. I think I’ll keep it as it is—just gaming, and it’s still under 80°C.
