Water cooling expert Koolance is ready with its full-coverage water-block for the dual-GPU AMD Radeon HD 6990 graphics card, which was launched a little earlier this month. The VID-AR699 from Koolance covers the obverse side of the PCB, cooling critical components there, including the two AMD Cayman GPUs, memory chips, the 450W-capable VRM, and the PEG bridge chip. Internally, the block is partitioned into three distinct bases, one over each GPU, and one over the VRM. The portions over the GPUs feature ribbed micro-fin structures to improve heat dissipation. The three bases are conjoined by a middle-plate that channels coolant through the three bases. The block is then topped off with acetal. The VID-AR699 measures 10.1" x 4.8 " x 0.8" (25.7cm x 12.2cm x 2cm), and weighs 2.25 pounds (1kg). Its primary material is copper with nickel-plating that minimizes corrosion over time. Its nozzle threading is standard G 1/4 BSP, though the package doesn't include nozzles. Koolance is pricing it at US $159.99 on its online store, it will be taking orders and shipping only after the 28th of this month. In related news, Koolance also announced that it's working on a full-coverage water block for the NVIDIA GeForce GTX 590, the VID-NX590, though there are no specifications or photos out, yet.
