Since there's no where to mount them (holes, etc) To attach heatsinks to the ram you'll have to use thermal epoxy glue. Thermal epoxy glue will help conduct heat to the ramsinks, as well as harden and make the ramsinks stick. When applying the epoxy be sure to only apply to the top of the ram, and to not get epoxy on the circutry as it can cause malfunctions. I have used Artic Silver Thermal adhesive and Artic Alumina, which I recommend over the silver as Alumina is ceramic based. You can read about both epoxy at http://www.articsilver.com/arctic_silver_adhesives.htm
