To address Roku overheating issues, start by ensuring proper ventilation around the device. Place it on a flat surface away from direct sunlight and other heat sources. Keep the vents unobstructed to facilitate airflow. If the device consistently overheats, consider investing in a cooling fan or heat sink specifically designed for Roku or similar streaming devices. Periodically clean the device with a soft brush to remove dust buildup that might impede airflow. If the problem persists despite these measures, reach out to Roku support for further assistance or consider upgrading to a newer model known for better heat management.
