Use laptop cooling pads

The vents are located at the hinge on Mac. The vents should not be blocked in any situation to maximize the airflow. If you have a habit of operating the Mac keeping it on lap, bed or on a cushion, the chances of overheating are increased as in this way you are blocking the vents thus not allowing the hot air to come out. So, it is advised to keep the Mac on a rigid surface like a table, books or cooling pads.

Most probably, your problem will be solved now. But in case the issue remains, consider going for resetting the SMC (system management controller).
