Included in the retail package is the heatsink itself with fans already attached, the Intel LGA2011 mounting kit, a baggie of "common parts" that includes two low-noise adapters, a Y-split cable and thermal paste, an instruction manual and a screwdriver.
As you can see, the heatsink assembly is identical to the original NH-D14 and is just as massive. The pictures pretty much speak for themselves - two large tower fin assemblies with the 140mm fan sandwiched between the two. The 120mm blows fresh air through the first set of fins and into the 140mm fan that further accelerates the air through the second radiator. Both fan cables are sleeved with a black braid and terminate into a 3-pin connector.
The Noctua name and logo are stamped across the top fin of each tower between where the six heatpipes terminate. You can also see that each fan uses a vibration reducer between it and the heatsink. The fans utilize a simple clip mechanism that attaches them to the heatsink. To remove a fan, use a finger to press the clip away and out from the heatsink to loosen. Rinse and repeat for the other side then either slide the fan up and out (middle fan) or just remove it for the outer fan 120mm fan.
