Install a liquid cooling unit: Premature without diagnosing the issue. Incorrect. * B. Monitor the core CPU and system temperatures: Confirms overheating and pinpoints thermal issues. Correct. * C. Reapply thermal paste to the processor heat sink: This may help but needs confirmation of the issue first. Incorrect. * D. Clean and test all fans: Ensures airflow but does not isolate the root cause immediately. Incorrect. Reference: Objective 5.2, which focuses on troubleshooting hardware components.
