Noise is always our main priority when it comes to high end fans. All of them can push gobs of air. All of them can include RGB. SOME of them can do those things AND have good static pressure, which these fans do not (They don't have terrible static pressure, but it could certainly be a lot better on a fan that is intended for use on a radiator).
A FEW of them can do two out of three of those things AND remain relatively quiet. These however, are not among those. They still might be a decent choice for the right buyer.
