EK-Quantum Vector RTX 3080/3090 D-RGB – Nickel + Acetal with Custom UV printed backplate EK-Quantum Vector RTX 3080/3090 D-RGB water block is compatible with most reference design (not Founders Edition) GeForce RTX 3080 and 3090 based graphics cards, but as always, we recommend that you refer to the EK Cooling Configurator for a precise compatibility match. The Vector water block directly cools the GPU, VRAM, and the VRM (voltage regulation module) as cooling liquid is channeled directly over these critical areas. These newly developed water blocks feature optimized flow paths which reduce hydrodynamic instabilities and vortexing (dead spots) inside the GPU water blocks. The base of the block is CNC machined out of high-grade electrolytic copper while the top is CNC machined out of durable black POM acetal. The watertight sealing is ensured by high-quality EPDM O-Rings. The brass standoffs are already pre-installed and allow for a safe and easy installation procedure. EK-Quantum Vector RTX 3080/3090 Backplate – Black is a CNC machined retention backplate made from black anodized aluminum, that fits all EK-Quantum Vector RTX 3080/3090 water blocks.
