Box, Contents & Bundle
The box has a photo of the fan on its face. This will help you easily distinguish the package of the black model from the white one. On the back side of the package, you will find some information about be quiet! and the product’s technical specifications. The bundle includes fixing bolts, push pins, four hard plastic washers, and rubber and hard plastic mountings. The rubber mountings are pre-installed.

The blades are optimized, according to be quiet!, for optimal performance and low noise output. The funnel-shaped fan frame also helps in performance and silent operation. As you will notice from these photos, the distance between the fan blades and the frame is small to allow for maximum static pressure.
You have two different mounting options: rubber and hard-plastic ones. For chassis, you better use the rubber, pre-installed mounts, while for radiators and heatsinks, the plastic mounts are the best choice.
Why would the white version have a higher noise normalizing RPM than the black version with the same aerodynamic profile? That is, the white version is significantly quieter than the black version?
