Overheating and thermal throttling under gaming load
When thermal interface material on the CPU or GPU degrades over time, or when heatsinks and fans accumulate dust, TUF Gaming laptops that previously ran smoothly will begin to throttle under gaming load, shut down during extended sessions, or run fans at full speed during lighter tasks. Older TUF models with RTX 30-series GPUs and 12th-gen Intel or Ryzen 7040 processors can show this degradation earlier given their age. Thermal service is the appropriate starting point.
