A cooling fan for mobile phones is a small device that attaches to the back of your phone and provides additional airflow to keep your device from overheating while playing games. It usually connects to your phone's charging port and is powered by the phone's battery.

Importance : As mobile games have become more demanding and graphics-intensive, they can put a lot of strain on your phone's CPU and GPU, causing it to generate heat. This can lead to performance issues and even damage to your device over time
