I'm curious about the wattage usage of the CPU. Perhaps you can verify it using OCCT or HWiNFO64. Just to have a reference... it was around 140W under heavy load.
This setting controls the maximum power your CPU can use, starting at 105W. When it hits 140W, the BIOS unlocks it for better performance, which is typical for some motherboard makers to prioritize speed over cooling. How are your temps during games?
It seems ASUS is handling things. The issue is that I notice reviews suggesting 'stock' is doing better than my 'stock oced'. I haven't tested any games yet; I plan to try them this weekend. Thanks!
Clock speeds in today’s CPUs rely on both temperature and power needs, so keeping the processor cooler might boost performance. In my setup, it hits around 4.85GHz for lightly loaded tasks and 4.55–4.6GHz during multithreaded tests like Cinebench or stress tests. What thermal paste are you using? Also, why did you mention your case side panel is open? It should stay closed for best airflow, assuming a proper fan configuration—typically front and bottom intake, top and rear exhaust.
Noted the maximum draw is 143W. Under similar loads with the same CPU model, temperatures stay below 180W. Power usage remains consistent despite the CPU change.
My setup remains active from the assembly/disassembly testing phase. As mentioned by the OP, I've used Noctua NHU1 and Artic MX4 with similar outcomes. The main difference was increasing the thermal paste amount, which reduced the temperature by about 3°C. This suggests a significant convex IHS issue, since higher thermal paste temperatures typically lower readings. Also, the offset voltage didn't behave as expected—setting -0.05 or -0.1 in both temperature and voltage settings produced identical results during Cinebench runs. Lastly, I couldn't locate core curve optimization in my BIOS.
In this situation (cinebench temps) adjusting the LLC (Load Line Calibration) could make a difference. This setting influences the voltage curve based on CPU usage. Each motherboard brand handles it slightly differently, so it's hard to recommend a specific choice. It's best to pick the one with greater voltage drop. When applying thermal paste, it's usually better to use more than necessary rather than less. Your IHS might not be perfectly uniform, but the paste will largely address this. Remember that with Ryzen chips, especially the newer models, the heat concentrates in a small area—the CCX die—making proper paste application crucial.
Enter PBO and adjust the PPT to 105, TDC to 90 and EDC to 80. This should lower temperatures by about 1% to 3%, keeping things comfortable at 60 to 78°C. I’m using a PPT of 115 with TDC 90 and EDC at 80, as suggested for air cooling BIOS settings. It seems my temps rarely exceed 75°C under load, which matches what works for my water cooling system. The 5800x is quite power-hungry, often drawing 30 to 40 watts more than required, making it a strong performance machine. I’ve been playing steadily for nearly two months now.
Apologies for the delayed response. I have submitted the return to the local distributor in my country.
