Laptop Overheating Due to Airflow Obstruction and Dust

Dusty Laptop Fan

This is the most common cause of overheating. Confirm by inspecting intake and exhaust vents for visible dust buildup or debris. Verify that the laptop is being used on a hard, flat surface; placing the device on soft surfaces like beds or blankets restricts airflow. If temperatures remain high after ensuring the surface is clear, use a light source to check if the internal heatsink fins are clogged with dust, which forces fans to work harder and reduces thermal dissipation efficiency.
