Well, whatever the "updated" model of the Pro was (the RDR2 bundle) is pretty quiet. Definitely not louder than the OG PS4 base model.
Need to check out the video, but don't you have to pull the side off to get to it? It's a neat addition, should make cleaning easy with a vacuum though I wonder if it's still "easier" than a simple air can spray. I hit my PS4 Pro after probably a year of not cleaning it and the vent holes around the exterior were gross, but cleaned in seconds.
