Routinely dusting and cleaning your PS4 will help extend its lifespan. This is because of the dust build-up that clogs the heat sink and makes the fan work double time. Sometimes, you might notice that your PS4 is working loudly and slowly. It can lead to overheating, malfunctioning, and and eventual shutting down if not addressed. With that, the fan in your system will work harder than necessary. The dirt, grime, dust, and any particles that float in the air can build up in your PS4 and trap heat. There are different reasons as to why you should clean your PS4.
