Is the Playstation giving you an overheating signal? My PS4 used to be REALLY loud and get pretty hot and one day it said it was overheating, so I took it to a different environment and it didn't do that again but was still loud so I cleaned the fans as I have had for about 3-4 years. That fixed it.
Point is- You just got it right? So the fans must not be a problem and there can't be dust so I would try to get another one if you REALLY think its a problem and they let you.
Other than that, unless you get an overheating problem(Like the console says it, TRUST me, you'll know, it acts like its a melt down lol) then I would say its fine.
If you don't feel air, maybe the fans don't need to, the console can get hot, mine does and my fans arent super loud. There built to withstand this pretty well.
Is it loud in ANY way? Like when it boots up or when you play a game, do you hear any form of sound? Because that would be the fan doing its job, you won't feel air most likely early in a game or at the home screen.
