Hey, you're dealing with a CPU temperature problem on your AMD Ryzen 5900X. After a long idle period, the system shows low temps but spikes when you use it. The GPU stays stable, but the CPU fluctuates between high and low speeds, causing noticeable lag in games. You've already changed thermal paste twice without improvement. Consider checking the cooling setup more closely or trying a different cooler if possible.
Software like this often gives inconsistent clock speed readings, but tools such as HWiNFO are more reliable. For precise timing, use the Effective Clock feature in Ryzen Master or HWiNFO. If you're dealing with overheating concerns that might lead to throttling, sharing details about your cooling setup, case placement, fan configuration, and room temperature would be useful. HWiNFO can also indicate if it's detecting throttling.
CPUs operate in this way. Your unit is getting too hot, improved cooling would be the best fix, aside from adjusting voltage settings.
What AIO and how old is it? It sounds like the cooler isn’t working correctly.
I checked several programs to verify the temperatures, and everyone agreed. I’m using an AIO cooler with two fans, specifically the Sharkoon TG5 Pro. All components—GPU and case fans—together make up 9 fans. I should note that the AIO is a relatively new model I purchased about a month ago, and it performed perfectly with my old CPU.
