My case is a Fractal Design Arc Mini R2, owners of the Arc series of cases will know that the front filter looks great but is very restrictive to airflow. So restrictive to the point where if I put my hand in front of the included fans I can't even feel any airflow. I like the look of the Corsair SP series but after checking benchmarks it turns that they aren't very good at their supposed function + they are very expensive. Ideas and input on this?
