Placing a PC on the floor can expose it to more dust, pet hair and debris than positioning it on a desk or shelf. This buildup restricts airflow, raises temperatures and may cause thermal throttling, reducing performance during demanding tasks such as gaming and potentially shortening the computer’s lifespan.

If floor placement is unavoidable, the article recommends using a stand or wheeled cart to raise the tower above ground level, avoiding carpets and humid areas, and leaving several inches of clearance around vents. Regular cleaning of filters and internal components, including with compressed air, helps prevent overheating; otherwise, heat-related wear could significantly reduce a system’s expected six-to-eight-year lifespan.
