Why each option
A PC frequently shutting down with loud fans, especially during a stress test, strongly suggests an overheating issue. The technician's immediate next step should be to monitor the core CPU and system temperatures to confirm overheating and identify the specific component causing it.
Installing a liquid cooling unit is a drastic and expensive solution typically considered after diagnosing and exhausting other thermal management options, not an initial troubleshooting step.
The symptoms of frequent shutdowns, loud fans, and immediate shutdown under stress are classic indicators of overheating; monitoring the core CPU and system temperatures will confirm this diagnosis and pinpoint which components are exceeding safe operating temperatures.
Reapplying thermal paste is a corrective action for overheating caused by poor thermal transfer between the CPU and heatsink, but it should only be performed after temperature monitoring confirms a CPU overheating issue.
Cleaning and testing fans addresses potential airflow issues, but it's a corrective action that should follow the diagnostic step of monitoring temperatures to confirm overheating is indeed the problem and not something else.
