[2021] Laptop CPU Overheating in CK3

Is that the CPU or GPU temp, or both?

What temps do you see before starting the game, and in the main game menu?

DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Please attach here your Documents/Paradox Interactive/CK3/pdx_settings.txt .
From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , error.log  

For the GPU temps, try reducing the frame rate cap from 144 to say 72 or even 60 - that should be fine for a non-action game like this.


If the problem is mainly the CPU , then it's a clear cooling system issue IMO, as there's nothing we can tweak in the game to reduce the CPU usage.

Clean out all air vents it has (compressed air cans are good for this). Make sure airflow to them is not blocked by anything like walls, books or whatever.
If that doesn't drop the temps enough, you probably have a faulty fan or a heatsink/thermal paste problem. You may need professional help at that point.
