I verified the mounting pressure, checked the thermal paste, and found four air bubbles. The GPU is cooling down to a peak temperature of 50°C. The Kombuster CPU reaches 90°C in just a few seconds. I’ve noticed 80°C under air cooling, which seems unusually high compared to what others report online. The 13059 Cinebench score appears a bit lower than some results.

Generally, new BIOS updates on most motherboards include this feature in PBO settings. It adjusts the CPU's voltage and frequency curve, allowing higher clock speeds at lower voltages. This boosts performance while reducing heat due to less power consumption. To enable it, you must apply a negative offset—typically around -30 is effective. A lower value may not work if the setting isn't properly configured. It also influences stability; -30 might cause issues for some users, but most CPUs handle -15 to -20 without problems.
Consider verifying the complete cooling system installation. The 5800X3D can overheat, but a 360mm water cooling unit should handle it better initially. A decent air cooler might perform even better, so a proper 360mm setup would be ideal. Ensure the CPU contact is correct, the pumps are functioning, the radiator is positioned right, and the fans operate as intended (static pressure vs. airflow focus).
