FrostyTech has posted a review on the Thermal Integration TI-V77L Heatsink
 
Thermal Integration made a lot of waves in the cooling marketplace with their introduction of the Thermoengine earlier this year. If you recall, the Thermoengine had two particular traits which helped to make it one very capable performing heatsink. The first aspect was of course the hollow center which decreased the overall amount of heat energy stored in the cooler, and the second was its very efficient fin design.
 
The TI-V77L follows in those same foot steps and uses Thermal Integration´s very efficient top-down design. The area under the fan motor is usually a dead spot for air flow and TI-V77L gets around this by using that section of material to transfer the heat from the processor throughout the body of the heatsink. Thus, all the cooling fins on the heatsink are located directly under the down draft created by the fan. As a further side benefit, the exhaust air blows directly down onto the top of the processor, adding further cooling into the mix.
