Multi-GPU liquid-cooling setups can be tricky business, and if not done well, could look ugly. To address this, Koolance launched the CNT-VDBx series of connecting blocks for multi-GPU setups running GeForce GTX 780 or GeForce GTX Titan graphics cards, with the company's VID-NXTTN full-coverage block. These connector-blocks each relay coolant in "parallel" over multiple graphics cards, while looking good. The connecting blocks are little more than metal tubing covered by acetal tops to match full-coverage blocks. These blocks are sold in pairs, for 2-point (two card, CNT-VDB1), 2-point over 3 slots (two card, CNT-VDB2), 3-point (three card, CNT-VDB3), and 4-point (four card, CNT-VDB4) variants, priced at $39.49, $42.49, $50.99, and $59.99, respectively.
