The new water blocks come in RGB and Copper flavors with Acetal and Plexi finishes. > All four water blocks that EKWB is launching today will be compatible with the reference PCB for the GeForce RTX 3090 and GeForce RTX 3080 graphics cards. Just to be sure, the PCB that comes with the Founders Edition graphics card is not a reference design and is actually a custom design by NVIDIA themselves. You can use the EK Cooling Configurator to make sure that your graphics card is compatible with the EK-Quantum Vector series water blocks.
