After having just reviewed the absolutely massive Noctua NH-D15, I have to say that the Evercool Venti seems rather small and lightweight. In reality it is far bigger than a stock OEM cooler, and clearly large enough to support a 120mm fan - so it isn't that small. There are a total of 4 u-shaped heatpipes, resulting in 8 paths for the fluid inside to draw heat sawy from the CPU and up into the cooler's fins.
The next two images show the Evercool branded 120mm fan included with the cooler. The unit is rated for 12V and 0.32A , with a speed range of 800 to 2200 RPM, air flow of 35.05 to 75.13 CFM, and a noise level of < 22 to 38.1 dBA.
When assembled, the fan will simply clip on to the tower of aluminum fins using a pair of spring clips included in the accessories.
The base of the cooler reveals that the heatpipes will make direct contact with the top of the CPU, so there is no intermediate layer used that might reduced the transfer of heat. The heatpipes have been flattened and the surfaces of the copper heatpipes and the aluminum filler in between are perfectly flat and uniform. The below left image shows the cooler without any mounting hardware installed, while the below right image shows that the two tabs have been attached to the cooler's base using the four included screws.
