Identified Symptoms and Troubleshooting Observations

1. Temperature Spikes Under Load:
2. During gaming sessions in PUBG and CS2, CPU temperatures escalate rapidly to 90–100°C, precipitating automatic shutdowns or reboots.
3. Idle temperatures fluctuate between 42–70+°C, increasing over time.

4. Even at idle, temperature spikes to near 97–100°C are observed, particularly during virtual memory loads.

5. System Errors and Blue Screens:

6. Common error codes include PAGE_FAULT_IN_NONPAGED_AREA, SYSTEM_SERVICE_EXCEPTION, and VIDEO_ENGINE_TIMEOUT_DETECTED.

7. Driver files such as navagio.sys and BEDaisy.sys have been implicated in crash logs.

8. Cooling System Performance:

9. The Noctua NH-U
