The EK-Quantum Vector FE RTX 3090 Backplate - Black is a CNC-machined backplate made of black anodized aluminum for the EK-Quantum Vector FE RTX 3090 - Special Edition water block. The backplate covers the rear of the graphics card PCB and serves as an aesthetic add-on. It provides additional passive cooling for the GPU core, the rear-mounted VRAM, and the back of the VRM area of the PCB. Due to the compact size of both the card and the water block, the backplate features a ribbed design for enhanced passive cooling performance and makes contact with the active part of the water block for true hybrid cooling. Included are mounting screws and thermal pads.
