The HD 7970 has been out for exactly 40 days now and Swiftech is already finishing its production of a HD 7970 full coverage water block. The block being a ‘full-coverage’ design covers the entire PCB on both sides of the card meaning all the VRMs, memory chips and the GPU chip itself are all directly cooled. The block is called the Komodo HD 7970 (much like Swiftech had previously released a Komodo HD 5870 and Komodo HD 6900) and takes up only a single PCI slot in width meaning you can easily run quad crossfire without any kind of space issues or airflow problems. It includes a single slot PCI bracket as most HD 7970s will come with a double bracket as standard.
The water block takes on a dark black design and even the fittings where the tubes get inserted are lucky enough to get a coat of black. The primary of materials of the design are a nickel-plater copper alloy for heat conduction and scratch resistance. According to Swiftech the block that covers the GPU chip has a o.25 by 0.25 Micro Pin matrix which apparently maximises heat dissipation to the coolant by increasing surface area. Swiftech have also made sure that the VRM has its own coolant chamber to ensure it recieves direct flow over it and is actively cooled. An illuminated red Swiftech logo is found on the water block bridge. The included backplate, which you wouldn’t normally get with a HD 7970, is made from brushed and anodised black aluminium. Swiftech has not announced any pricing or availability information just yet but we anticipate the product should arrive within a month or so and given the fact the HD 6900 variant of the Komodo cost $140 we expect this to be slightly cheaper as the HD 7900 series cards are slightly smaller.
