Who it fits

Key Specs Explained

Color: Black

This finish provides a uniform, dark appearance that matches the original Founders Edition shroud. It helps the block blend seamlessly into a build without drawing unnecessary attention. If you prefer a stealth look, this option works well. You can choose clear if you want to see the internal copper or nickel plating. The color does not affect cooling performance.

Length: 11.8 inches

This length covers the full PCB of the RTX 3080 Founders Edition. It ensures the cold plate touches the GPU die, VRMs, and memory modules. This full coverage is critical for effective heat transfer. Shorter blocks often leave hot spots near the memory or power delivery components. Check your case clearance to ensure this length fits without hitting other components.

Width: 7.11 inches

This width spans the entire card, including the backplate area. It ensures the mounting pressure is distributed evenly across the PCB. A wider base reduces thermal resistance by covering more surface area. It also helps manage heat from the voltage regulators on the sides. Verify that your case supports this width to avoid interference with surrounding hardware.

Height: 2.05 inches

This height determines how much vertical space the block occupies above the GPU. It must fit under your case’s top radiator or near other components. Measure the distance from the PCIe slot to the nearest obstacle. If you plan to run SLI or Crossfire, check if the height allows clearance between two cards. This dimension is vital for case compatibility.

Weight: 5.1 pounds

This weight indicates a robust construction using solid copper and nickel plating. A heavier block often suggests better material quality and heat capacity. However, it places more stress on the GPU PCB and PCIe slot. Use a support bracket to prevent sagging over time. Compare this weight with lighter aluminum blocks to understand the durability difference.

Design and Build Quality

The block features a full coverage design that extends across the GPU surface. According to the listing, it is crafted from high-quality materials to ensure durability and effective heat transfer. The finish is black, providing a uniform appearance that matches the original Founders Edition shroud. This helps the component blend seamlessly into your build without drawing unnecessary attention. If you prefer a stealth look, this option works well. You can also choose clear if you want to showcase the internal flow.

The dimensions are substantial, measuring 11.8 inches in length, 7.11 inches in width, and 2.05 inches in height. The unit weighs 5.1 pounds. These specifications indicate a heavy, solid construction that requires adequate support within your case. The size ensures comprehensive contact with the graphics card components. You must verify that your case has enough clearance for this height and length.

It is designed to fit standard G1/4 thread fittings, allowing you to connect standard tubing and fittings for your loop. The design is SLI/Crossfire compliant, meaning it supports multi-GPU setups if you plan to use multiple cards. This flexibility is useful for users building high-end workstations or gaming rigs with multiple accelerators. The layout is straightforward, focusing on coverage and compatibility rather than complex features. You get a reliable, spec-driven component for your custom loop.

Setup And Everyday Use Guide

Installing this water block requires careful planning. The unit measures 11.8 inches in length and 7.11 inches in width. You must ensure your case has enough clearance for these dimensions. The height of 2.05 inches also matters for your cooling loop layout. The block weighs 5.1 pounds. This mass is significant. You need to support the GPU properly to prevent sagging or stress on the motherboard slot. The listing states it is SLI and Crossfire compliant. This means you can use multiple units in a multi-GPU setup if your system supports it. The block is designed for standard G1/4 thread fittings. You will need compatible tubing and connectors to attach it to your reservoir or radiator. This is a standard size, so most fittings will work. Daily use involves filling the loop with coolant. You must check for leaks after the initial fill. The black finish helps the block blend into most builds. It does not draw attention away from other components. The full coverage design aims to cool the entire GPU surface. This includes the memory and power delivery components. You should monitor your temperatures during the first few weeks of use. The specs suggest a robust construction. It is built to last. However, proper installation is key to its performance. Ensure all connections are tight. Avoid over-tightening fittings. The block is not a plug-and-play solution. It requires knowledge of liquid cooling. If you are new to custom loops, seek advice before starting. The design is straightforward. It fits the RTX 3080 Founders Edition specifically. Do not expect it to fit other cards. The weight and size are fixed. You cannot adjust them. Plan your case and loop accordingly.

Before You Buy This Block

You need compatible G1/4 threaded fittings for your tubing. The listing confirms it supports standard connections, simplifying your loop design. Since it is SLI and Crossfire compliant, you can use it in multi-GPU setups if your motherboard allows. Check your case dimensions carefully. At 11.8 inches long and 7.11 inches wide, it covers the full card. The 2.05-inch height may interfere with nearby PCIe slots or case walls. You must also plan for a pump and reservoir. This block is for custom loops only. It does not include fans or tubing. Compare its weight of 5.1 pounds to other blocks. Heavier units may stress the GPU PCB over time. Ensure your RTX 3080 Founders Edition matches the block’s specific mounting holes. Verify the color option, black or clear, fits your aesthetic. Proper maintenance requires clean water and periodic flushing to prevent algae or debris buildup.

Check before you buy

• Verify G1/4 threaded fitting compatibility with your existing tubing.
• Measure case clearance for the 11.8-inch length and 7.11-inch width.
• Confirm the 2.05-inch height does not block other components.
• Check multi-GPU support if building an SLI or Crossfire system.
