In this review Frostytech is testing the new Titan TTC-NK85TZ Fenrir heatsink, a good CPU cooler from a manufacturer which has had a spotty past. If you can find the Titan TTC-NK85TZ Fenrir you'll find it equivalent to models like the Sunbeam Core-contact freezer. Like many tower heatsinks, the TTC-NK85TZ Fenrir heatsink has four exposed 8mm diameter direct contact heatpipes at the base. Weighing it at roughly 550grams, the TTC-NK85TZ Fenrir is compatible with both Intel socket 775, 1366 and the entire family of AMD socket 939 to AM2+ processors.
