The Spirit RS can be used on DDR and DDR2 memory modules and includes two separate contact patches to maximize compatibility among single-sided and double-sided memory modules. The Spirit RS heatsink is separated into two compartments - the area that comes in contact with the chipset is made of extruded aluminum to effectively transfer the heat to the heatpipes. The heatpipes then transfers the heat towards the aluminum fins on top of the unit. The thermal efficiency of the Spirit RS is extremely high and can quickly cool off the memory module. In addition, the heatpipe and the heatsink are adjustable in angle so that the users can install them however way they would like to minimize compatibility issues and increase performance efficiency.
