Best answer: Your PlayStation 4 Pro may get loud due to the fans needing to work harder to dissipate heat. Repositioning and cleaning your PS4 Pro with a can of compressed air is the first thing you should do when you notice it happening.
Keep your PS4 Pro clean and comfortable
The most common cause of noise in many consumer electronics is due to a spinning fan, and that's no less true when talking about the PS4 Pro. Fans work to help move heat away from the PS4 Pro's internal components, as overheating could lead to hardware failures.
As such, it's important to keep your PS4 Pro as clean as you can. Be sure to give its external a good wipe down at regular intervals, and for the hard-to-reach areas — such as the cooling vents and inside the disc tray — you can use compressed air to ensure all its airways are unblocked.
Another measure you can take is to ensure your PS4 Pro has as much breathing room as possible. Try and position your console in such a way that there are a few inches of space on all sides. If the console is too close to a wall or door, the heat can blow back onto itself and make the console hotter, which causes the fans to spin up more.
What else can cause the PS4 Pro to get loud?
One less common cause of loudness in the PS4 Pro is the disc drive. This is typically only an issue during your initial game install, as the PS4 is designed to install all game data to your hard drive so as to limit the wear and tear on the disc drive. As such, you'll most likely only hear noise from it when you're in the process of installing a game.
There are times when the PS4 Pro's disc drive will spin up after installation, namely when you first insert the disc and boot your game up. This is because the PS4 needs to read the disc to verify that the game you're trying to play is actually inserted in the console. This should subside within a few minutes.
Is there a way to stop this problem before it happens?
As mentioned before, the best thing you can do for your PS4 Pro is to make sure that it has room to breathe. If you're keeping it in an enclosed space it'll be susceptible to overheating and the fans will get much louder as a result as they attempt to cool the console. Fixing overheating issues thankfully isn't too difficult, but it's smart to stop the problem before it even happens.
Using a HIDEit PS4 Pro Wall Mount is the perfect way to mitigate this problem, especially if your entertainment center or desk just don't have the room necessary.
What if the noise doesn't improve?
If the fans continue to roar after cleaning and moving your PS4, or if the disc drive is spinning outside of the scenarios discussed above, it may be a mechanical failure that requires further attention. We'd advise contacting Sony's PlayStation division in that situation.
Sony can help you troubleshoot your PS4 Pro's issues, and if they can't, then they can initiate a warranty or repair process to help get you situated. It's worth noting that a loud PS4 Pro doesn't necessarily mean anything is gravely wrong with the console. It could very well work just fine. But if you want peace of mind or just can't stand the noise, call Sony. You can get started with that right here.
