Who it fits

Alphacool Backplate Key Specs

Material: Acrylic

The top cover is made of acrylic, which allows you to see the internal copper block and any liquid flow. This material choice prioritizes visual clarity over the durability of metal. You get a clear view of the cooling loop, which is ideal for custom builds where aesthetics matter. Acrylic is lighter than metal, making the unit easier to handle during installation. It also resists corrosion from coolant, ensuring the look remains consistent over time without the risk of tarnishing like bare metals.

Color: ARGB

The unit features addressable RGB lighting, allowing you to sync colors with your motherboard or controller. This means you can create specific patterns or match the rest of your PC build. ARGB offers more control than standard RGB, letting you set individual LED colors. This is useful for creating a cohesive look across multiple components. If you already have an ARGB setup, this backplate integrates seamlessly. It adds a customizable visual element to the back of your graphics card without requiring separate power cables.

Dimensions: 11.4 x 4.92 x 0.51 inches

These physical measurements define the footprint and thickness of the backplate. The length and width ensure it covers the GPU properly, while the slim profile minimizes interference with nearby components. You must check your case clearance to ensure the unit fits without touching other parts. This size is specific to the RTX 3080 and 3090 FTW3 models. Comparing these dimensions helps you determine if it fits your specific card variant and case layout before purchase.

Weight: 2.5 pounds

The unit weighs 2.5 pounds, which is substantial for a backplate. This weight comes from the nickel-plated copper construction, which aids in heat dissipation. You need to ensure your graphics card bracket can support this load without sagging. Heavy components can stress the PCIe slot over time if not supported properly. This weight indicates a robust build quality but also highlights the need for adequate case support. It is heavier than plastic alternatives, offering better thermal mass for active cooling.

Design and Build Quality

The unit is constructed from nickel-plated copper with an acrylic top. According to the listing, this material combination allows you to see the internal copper block and liquid flow. The acrylic cover prioritizes visual clarity rather than the durability of metal. You get a clear view of the cooling components inside. The backplate is designed to fit GeForce RTX 3080 and 3090 graphics cards. It adds active cooling to the rear of the GPU. This increases overall cooling performance by managing heat on the back of the card.

The dimensions are 11.4 inches in length, 4.92 inches in width, and 0.51 inches in height. The weight is 2.5 pounds. These measurements ensure it covers the standard area of supported graphics cards. The slim profile means it does not interfere with surrounding components. It sits flush against the back of the PCB. The ARGB finish allows for lighting customization. This matches the aesthetic of other Aurora series components. You can integrate it into a cohesive RGB setup.

Connection options include G1/4 inch internal threads on the top side. There are also side ports suitable for 5/3mm hoses. This flexibility lets you choose how to route tubing. You can use hard tubes or soft hoses. The design supports both variants easily. You do not need special adapters for standard fittings. The layout is straightforward for most water cooling loops. It integrates well with existing Alphacool hardware.

Setup And Daily Operation

Setup requires integrating this backplate into your existing custom loop. The unit provides two distinct connection methods for flexibility. Variant one places G1/4" internal threaded inlet and outlet ports on the top surface. You can use standard fittings and hard tubing to route coolant directly from the top. This layout keeps connections discreet and out of the way of other components. Variant two offers side-mounted ports compatible with 5/3mm hoses. This option suits users who prefer flexible tubing routing from the sides. Both methods allow the backplate to function as an active cooling component. It attaches to GeForce RTX 3080 and RTX 3090 graphics cards. The listing confirms compatibility with Alphacool Eisblock Aurora Acrylic GPX-N GPU custom water coolers. It also works with Alphacool Eiswolf 2 GPU AIOs. You must verify your specific card model matches the FTW3 designation before installation. The backplate measures 11.4 inches in length and 4.92 inches in width. Its height is just 0.51 inches, ensuring it fits within standard case clearances. Weighing 2.5 pounds, the nickel-plated copper block adds mass to the GPU. This mass helps dissipate heat from the rear of the card. Daily use involves maintaining your loop’s coolant level and pump pressure. The acrylic top allows you to monitor internal flow and copper block visibility. The ARGB lighting adds visual customization without affecting cooling performance. You simply ensure all connections are secure and leak-free during initial setup. Once installed, the backplate operates passively as part of your active loop. It does not require separate power or software control for its cooling function. The design focuses on thermal transfer rather than electronic features.

Before You Buy This Backplate

You should verify that your graphics card matches the specific FTW3 variant before purchasing. This backplate is designed exclusively for that model. It works best when paired with Alphacool Eisblock Aurora Acrylic GPX-N GPU custom water coolers or Eiswolf 2 GPU AIOs. You must check the compatibility list to ensure your specific card is supported. The unit adds active cooling to the back of the card, which can improve overall thermal performance. You will need appropriate fittings and tubing to integrate it into your loop. The G1/4" ports or side hose connections require careful planning. Acrylic tops need gentle cleaning to avoid scratches. This accessory complements existing custom loops rather than replacing them. It is ideal for users who want enhanced cooling and aesthetics without building a full new system from scratch.

Check before you buy

• Confirm your GPU is the specific FTW3 variant.
• Check compatibility with your current Alphacool cooler.
• Ensure you have suitable G1/4 fittings or tubing.
• Plan the coolant flow path for the backplate.
