Your CPU is running hot?
Hello, your recent upgrade to the Ryzen 7 5800X3D with the RX 7800 XT is great. While playing Battlefield 2042 you observed temperatures reaching up to 84°C. I understand these temps are higher than the Ryzen 5 5600 but it’s normal for this model. Idle temps hover around 40-45°C, which makes sense compared to gaming spikes. Using a Be Quiet! Dark Rock Pro 4 for cooling helps keep things stable. Thanks for sharing your experience!
An 84 peak is completely fine, focus on the typical values while playing. Occasionally spikes appear when shaders or similar tasks load. This often happens when people assume the highest CPU temperature they've reached is the actual limit. So it's okay; consider your room temperature and thermal paste choice. Check your average temperature—if it's around +80°C after an hour of gaming, you might be in trouble. Otherwise, you're doing well.
Thanks for the quick reply! Yes, it really does depend on the game and the resources used. In games like Rainbow Six Siege and BF2042, which are CPU-intensive, temperatures can rise significantly. So yes, you can likely handle gaming around 80°C without issues.
You haven't used R6S recently, so it's unclear what you were doing. Yes, you should check the cooler for proper contact and apply enough thermal paste.
I received the components this morning and installed them. The system has been running since then. Tomorrow I’ll inspect the CPU for any gaps in thermal paste. I used a sufficient quantity but avoided excess so it wouldn’t seep around after the cooler was placed. If any gaps remain, can I simply add more to the existing layer? Or would I need to clear everything and reapply?
Remove the cooler and inspect the spacing on the cold plate and CPU to confirm complete coverage. It’s recommended to clean and reapply thermal paste, as adding more and trying to refit might trap air bubbles, forming gaps that prevent effective heat transfer.
5800X3D stands out for its elevated idle temperatures compared to other chips, especially noticeable during idle mode. This behavior is inherent to the CPU architecture. Battlefield (the Frostbite Engine) also tends to be a CPU-intensive application, utilizing multiple cores and AVX instruction sets that typically generate more heat than non-AVX operations. Essentially, it's just a matter of thermal management in these systems.
