    At a certain point, the sheer amount of fan housing mass is blocking air flow more than anything else.

    Forget about jet engines. This thing probably sounds more like a helicopter at close range! The ironic part of this is that it could actually lead to power supply issues, which can be just as bad…

      For shits amd giggles, I put a couple of industrial 10W fans in my PC once. That probably still made more noise than this. It also created so much overpressure that I could feel air escaping the tower from every little hole or crack. You could hold a piece of paper to the side of the pc, and see it moving because of the air escaping between the side panel and the main hull.

      But if these are normal fans (max maybe 1,5W), then the amount of power drawn will be the same as a couple of hardrives.

      No

      The same amount of airflow is being pulled through, and your static pressure would go up meaning the fans actually need to work harder for the same effect.

      I know it’s done in servers with high rpm 40mm fans. To create extra static pressure. But it didn’t work with 2x 120mm fan on a aio in my testing.

      They would likely perform worse. If (“if”, ha) those fans are not in perfect sync, they’re going to obstruct airflow. Also, consider that each fan introduces both audible noise and perturbations in the airflow which in turn, also will cause noise.

      Incidentally, I have (almost) that very same case, an Antec P182. Mine has a super-quiet PSU fan, and a ginormous heat pipe cpu cooler (HR-1 if you’re curious) with one fan … and that is plenty.

      Probably would only be slightly better, but it would be significantly louder since multiple fans creates significant turbulence.
