The technician should remove dust from the intake fans as part of the preventive maintenance plan.

At a construction site, there is usually a lot of dust in the air, which quickly builds up inside PCs.

This dust can clog intake fans, block airflow, and cause components to overheat, eventually leading to hardware failure.

Regularly cleaning and removing dust from the intake fans helps keep the cooling system efficient and extends the life of the PCs.
