With the new Alphacool D-RAM modules all memory blocks can easily and quickly be equipped with water coolers! With these modules, the memory blocks are clamped in the modules (with the attached thermal pads) to achieve optimum cooling results . The seperately available D-RAM coolers are added and screwed in. We recommend a very thin layer of thermal paste applied between module and cooler for an optimal heat transfer. Note: A thicker thermal pad must be used on one side for single-sided memory blocks which is not included and has to be bought seperately. Includes 2x module for D-RAM, 4x thermal pads, and fitting accessories.
