PlayStation 4 overheating is a common problem that can occur when the console is used for extended periods of time. To fix this issue, you will need to take some measures to prevent it from happening. One way to do this is by using a coolant and air filter system. Another solution is to change the PS4’s firmware. If you have not done so already, you should make sure that your PS4 is up-to-date with the latest security patches. Additionally, you can try changing the power supply unit or by using a new fan. If all of these measures do not work, then you may need to take your PlayStation 4 into an authorized service center for repair.
