Be Quiet has an easy way of labeling their air cooled products, dividing them into three classes:

Pure Rock: Entry level quiet coolers (2 single tower coolers)
Shadow Rock: Premium coolers at an attractive price (Single Tower, Top Flow and Low profile models)
Dark Rock: High performance coolers (Single & double tower and Top flow model)
The Shadow Rock premium series include single-tower, slim, top-flow and low-profile cooler designs. They deliver exceptionally high cooling performance and remarkably quiet operation, all at highly attractive prices in the premium CPU cooler segment. Whether your PC is built for advanced gaming, demanding graphics applications or hi-res multimedia functionality, Shadow Rock coolers will impress you with their combination of features and price point.

Today we introduce to you the Top Flow model, the Shadow Rock TF2. Why a Top Flow cooler model? Well these models allow better cooling dissipation in enclosures with restricted space; most medium or high end Tower coolers are in general higher than 140mm, meaning your favorite enclosure must be wide enough to support the cooler of preference.
