Replaced the PS4 fan that turned on sometimes and even when it was on; it doesn't spin fast enough to keep it cool. After replacing the fan, the PS4 can stay on and keep itself running without overheating. I personally don't notice any loud noises that a new fan might make. There is only a slight hum, if any. The fan was in my PS4 and has been working great for 5 days now. 6/26/21 I hope to see how he behaves in the future.
