Backplate EK Water Blocks Quantum Vector2 Aluminium Silver RTX3090 133mm x 282mm x 17.6mm

The EK Water Blocks Quantum Vector2 Aluminium Silver RTX3090 backplate is a machined aluminium retention plate designed specifically for RTX3090 graphics cards. It measures 133 mm in width, 282 mm in depth and 17.6 mm in height, and is finished in silver. The backplate is supplied with a mounting mechanism and thermal pads to simplify attachment and to improve thermal contact with the graphics card's components. It covers the full length of the graphics card PCB and provides passive cooling for the backside of the GPU core and voltage regulation components while contributing to a clean, uniform appearance.

Advantages

This aluminium backplate offers a rigid structural reinforcement for the graphics card PCB and a consistent silver aesthetic that matches aluminium-based builds. The included thermal pads and mounting mechanism enable straightforward installation and help transfer heat away from the rear side of the GPU and VRM. As a passive cooling element, the backplate helps reduce hotspot temperatures on the PCB without requiring additional power or moving parts.

Suitable for (tasks / use cases)

• Improving passive cooling of RTX3090 graphics cards by providing additional heat spread on the PCB rear.
• Reinforcing the graphics card PCB to reduce flex and support heavy cooling assemblies.
• Achieving a uniform silver aesthetic in custom PC builds that use aluminium or silver-accented components.
• Use with water-cooling setups where a matching retention backplate is required for full-coverage appearance and thermal management.

Key specifications

• Material: machined aluminium
• Finish: silver
• Dimensions (W × D × H): 133 mm × 282 mm × 17.6 mm
• Includes: mounting mechanism and thermal pads for installation

How to use

Prepare the graphics card by powering down the system and removing the card from the motherboard. Remove any existing backplate or protective covers according to the card manufacturer's instructions. Position the EK Quantum Vector2 Aluminium Silver backplate over the PCB so that mounting points align, place the supplied thermal pads where indicated to ensure thermal contact with the VRM and GPU rear, and secure the backplate using the included mounting mechanism. Reinstall the graphics card into the system and verify proper seating and clearance within the case before powering on.

Usage recommendations

Use the supplied thermal pads and mounting hardware; ensure thermal pads contact the intended components and are cut to fit where necessary. Check compatibility with your specific RTX3090 card revision and any installed water block to confirm mounting hole alignment and clearances. Avoid overtightening mounting screws to prevent PCB stress.
