Question Ryzen 7 2700X started overheating

[Da_Gaz]

Suddenly, after ~4 months after installation, my processor started overheating under medium loads and has begun powering itself off. I am using my stock cooler. I set the fan to max. I was overclocking before the issue occurred. My case is be quiet 800. Can you guys please help me?
