When you are liquid cooling multiple GPUs it becomes difficult, especially if you want to make it look good. Koolance knows this and has launched their CNT-VDBx series of connecting blocks for multi-GPU setups running GeForce GTX 780 or GeForce GTX Titan graphics cards. These connecting blocks are made to be used with the company’s VID-NXTTN full-coverage block.
These connector blocks will relay your coolant in “parallel” over multiple graphics cards and will have a pretty cool look as well. The blocks are metal tubing covered by Acetal tops to match the full-coverage blocks.
The 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.
