Good news for all the watercooling users out there, EK Waterblocks
are designing a full cover water block for both the ROG MATRIX HD 7970, and the MATRIX HD 7970 Platinum. EK expects its EK-FC7970 MATRIX block should be ready to ship in late February, and will provide a high-flow cooling solution for the GPU, VRM and RAM, although there is no confirmation of a back-plate being manufactured as of yet.
Are you lucky enough to own a MATRIX HD 7970 and plan on watercooling it? Let us know in the forums.
