EK-RAM Monarch Module is a heatsink adapter which allows virtually any (DDR-)SDRAM memory module (of any generation) to be liquid cooled in conjunction with EK-RAM Monarch series water blocks.
Each heatsink consists of two separate plates while the DIMM memory module is sandwiched in between. Heat transfer between the memory module and aluminium heatsink adapter is ensured by the use of an enclosed thermal pad.
EK-RAM Monarch Modules set contains two (2) EK-RAM Monarch Module Adapter heatsinks. Each of these items are made of CNC machined high quality aluminium and feature nickel finish (Nickel) or black anodized finish (Black).
