be quiet! Dark Rock TF 2

Two 135 millimetre fans, seven heatpipes and a fighting weight of 945 grams: the be-quiet cooler outperforms the rest of the test field in terms of material usage and cooling performance, and at the lowest noise level. The downside is the high price and the height of 134 millimetres...

The be quiet! Dark Rock TF 2 exhibits excellent cooling ability and near-silent operation, though it faces stiff competition from its own be quiet! brethren. But as either a performance option where the clearance is the primary limiting factor, or for those who favour downdraft coolers, it's a solid choice.
