What should be done if a service technician finds that the internal fans are running constantly?

• A. Consider replacing the power supply
• B. Inspect for dust buildup and overheating issues
• C. Perform a factory reset
• D. Check for external devices connected

Answer: (B)

When a service technician discovers that the internal fans are running constantly, inspecting for dust buildup and overheating issues is the most appropriate action. Constant operation of fans often indicates that the system is trying to compensate for high temperatures. Dust accumulation can block air vents and clog fan components, leading to inefficient cooling and potentially causing components to overheat. By removing dust and ensuring that the cooling system is functioning properly, the technician can help restore optimal airflow and thermal management, which may reduce the need for the fans to run continuously. Other considerations, like checking external connections or performing a factory reset, may not directly address the root cause of the fans' constant operation. Additionally, while a power supply issue could theoretically affect how systems operate, it is less directly related to fan behavior compared to overheating concerns. Therefore, thorough inspection for dust and overheating is critical for maintaining the overall health and performance of the computer system.
