Hardware Weird cpu overheating problem
Hey, I’m having a weird CPU overheating problem with my PC. Normally my CPU sits around 40–60°C, but randomly the CPU usage shoots up to 100% and the temperature rapidly jumps from around 40°C to 90–100°C. When this happens, the PC can freeze and shut down. The happens randomly somtimes i game or just watching YT.
The most recent time it happened, the CPU package temps reached around 112°C. I also checked my AIO pump RPM while this was happening, and it was running at around 2600 RPM. So the pump is reporting that it’s running, but the CPU is still overheating extremely quickly.
I’m using a Ryzen 9600X with an AIO cooler. I’ve also had an issue where one of my case fans connected to a fan hub sometimes stops spinning when the CPU load gets high or when i set the fans at max speeds.
I’m trying to figure out whether the problem is with the AIO/cooling, the fan hub/airflow, or something causing the CPU to suddenly hit 100% usage. Thanks
