I can't really comment on the aesthetic as I bought them simply for being a cheap SP option. As luck has it, the orange ones were only $13 a piece on amazon. If you need airflow, buy airflow. The pricing is usually pretty close, and they're better suited for the task.
As for loud... I mean, it's honestly rare they have to rev up that much, but my setup is mostly rads. They're.... an ambivalent "ok".
Also, I believe that corsair fan is ALSO static pressure. You want one of their AF models if airflow is the goal. AF120 or whatever, that seems to be the scheme Corsair uses.
