Top down cooling has its advantages, though tower cooling is usually the preferred method given its compact footprint. In this review Frostytech is testing out a heatsink from Titan that aims to satisfy both tower and top-top heatsink designs, in one. The Titan Fenrir Siberia Edition TTC-NC55TZRB heatsink is built around five 8mm diameter copper heatpipes which extend in two directions from a copper base block to independent fin stacks, essentially making one large CPU cooler from separate 'tower' and 'top-down' heatsinks.
