As you can see, the HR-07 is a new type of cooler, based upon the principles of Heatpipe cooling. Heatpipes have been very popular the last couple of years when it comes to CPU and GPU cooling, but for ram cooling, this has not been done before. The coolers have a shiny silver finish, and can, besides the cooling effect, make your rig in a windowed case look that little bit more "extreme" as well. The finish of the cooler is extraordinary: I could not detect one sharp edge or unfinished metal fin on the entire cooler. Thermalright made sure the quality is up there with the very best.

Every cooler has a double heatpipe system, which leads heat away from the heat spreader plate which is in contact with the ram chips, towards the multitude of small metal plates, or fins if you like, which sit on top of the heatpipes. All of these fins are in fact small "radiators", spaced closely together. The air inside your case can move between them, and heat can be moved away by a convective airflow between the fins. Furthermore, small holes are made into the fins to allow air to circulate even better and allow for better ventilation in passive mode. In addition to the passive mode, Thermalright has built in the possibility of active cooling when you're using dual ram coolers, in dual channel operation. The fans can be directly attached to the coolers, and can provide active airflow to offer even better convective heat dissipation.
