Detailed explanation-3: -Give it some space (airflow, laptop cooling pads) Make sure the airflow around your computer is open and there’s proper ventilation. And don’t put your laptop in a case while it’s awake. Keeping air circulating around your computer helps keep your hardware cool and reduces laptop fan noise.
