If you're looking for a bit of insight into the cooling world, pay close attention to this type of heatsink from Thermal Integration. The TI-RV108N is blessed with an "X-form" vertical extrusion and copper core design that instantly puts it spades ahead of the competition. The reason is simple, the cool exhaust air from the 4000RPM fan exits the heatsink directly at the processor, adding a further layer of cooling which is more than just inconsequential. Take into consideration the 28mm diameter copper slug at the very center of the Thermal Integration TI-RV108N, and you have all the ingredients necessary for one very capable socket 478 heatsink. Now let's find out what the thermal tests have to say!
