Be quiet's Dark Rock line of CPU coolers are their high-performance line meant to handle the most extreme processors and thermal loads out there. While most of the coolers in the line are tower coolers there is one that is different, it is the Dark Rock TF. The Dark Rock TF or Dark Rock Top-Flow is a C-type cooler that features two powerful nickel-plated aluminum heat sinks and two 135 mm SilentWings cooling fans. Be quiet calls this cooler a compact cooler, but it is one of the larger C-type coolers that we?ve seen. It is supposed to offer one of the best performance-to-noise ratios in its class. Let's get it installed and see what it can do!
