The EK-Quantum Vector 3 FE RTX 5090 – Plexi is a high-performance water block designed exclusively for the NVIDIA GeForce RTX 5090 Founders Edition. With a new, expanded cooling engine, improved thermal pads, and a precision-engineered gasket system, this block ensures optimal heat dissipation for the GPU core, VRAM, and power stages. The included backplate provides additional passive cooling, while EK-Matrix7 compatibility simplifies loop integration. Included Full-Coverage Backplate The EK-Quantum Vector 3 FE RTX 5090 water block features a black anodized aluminum backplate assembly that enhances both cooling performance and structural integrity. Unlike standard backplates, this assembly provides passive cooling for the MOSFETs located on the backside of the block, ensuring stable power delivery under load. Additionally, the backplate serves as the main structural element of the GPU's PCB, connecting all components and providing essential rigidity to prevent PCB flex and stress over time. The assembly also integrates the stock lighting module from the original cooler, illuminating the EKWB badge for a sleek and refined aesthetic.
