Inside the packaging you have the items shown below; the cooler, a bag full of fan mounting hardware and thermal pads, and a fairly brief user's manual. When used alone it would be possible to rig up a fan, but paired up in a dual channel configuration is where the HR-07 would work best allowing the included hardware to support a 72mm, 80mm, or 92mm fan (not included).
Those familiar with their products will recognize the HR-07 as one of Thermalright's by the distinctive design. The monochrome "silver" finish achieved with a tight array of aluminum cooling fins and nickel plated heatpipes/base has become the traditional look of all coolers from Thermalright. Even so, the HR-07 is nothing like any memory cooler I have seen, and the double heatpipe design is quite foreign looking to me.
The concept of the design makes sense though, and what you have is a heavyweight heatspreader with a heatpipe on either side that draws heat up to a pair of cooling fins that will be situated in the moving air inside a typical system.
The design of each HR-07 allows for passive cooling using the system's fans for assistance, but using two HR-07s in a dual channel memory configuration allows the user to take advantage of mounting slots and hardware to install a fan of their own. The slot visible in the bottom front portion of the cooler, as shown in the image below, is where the fan hardware would attach and provide a flexible mount that could be adjusted to accommodate the variety of fans mentioned.
Just by taking a look at the images above it can be seen that the HR-07 is well built, and it is by far the most heavy duty memory cooler I have seen. Compared to the rather flimsy aluminum or copper heatspreaders found on most memory, this thing looks ready for war.
