CPU Overheating For No Reason? Here is How to Fix It
For instance, the max. operating temperature for my Ryzen 5 5700G APU is 95 C. But when it reaches such a high temperature, it thermal throttles, causing a significant loss in performance. Although that''s a good thing (prevents the CPU from overheating further), you wouldn''t want a slower speed with reduced performance.
