My ps4 started making this weird loud rumbling near the fan area. Not only that but when it gets really loud my ps4 overheats and shuts down. I’ve taken it apart and cleaned it but it still continues. I’ve also noticed that where the thermal paste should be there isnt any. It also gets really hot in that area too.
Hi @justformy3ds , Is the fan working OK, you didn’t say? Here’s a link to the ifixit PlayStation 4 Fan Replacement guide which may be of some help. It also contains a link on how to replenish the thermal paste on the processor.
