I am having an issue that just suddenly popped up where my computer is starting to overheat. PC will boot up fine, work fine for a few minutes and then I start getting a deterioration in frames when doing things on the computer. I am not running anything difficult and the CPU usage is around 10% in the task manager.
I have done basic troubleshooting such as: Replacing the thermal paste, cleaning any dust that was visible out of the radiator, fans or on the case, and made sure that the screws on my AIO were tight enough so that there wasn't any issues with there not being enough contact between that and the CPU. I also made sure that there wasn't any issue with the directions the fans were spinning, everything as far as airflow goes is correct and all fans are spinning.
I am on Windows 10, 750W power supply, and i9-9900k, I have an AIO that is a fractal s36 Prisma.
Any help or suggestions would be greatly appreciated
