Who it fits
Good fit for
You should consider this block if you have an RTX 4080 card with a compatible PCB layout. The 10mm copper thickness suits users who want robust thermal mass without excessive weight. The lightweight design helps protect your PCB from deformation. If you need 5V ARGB synchronization, this model supports that standard. Check your card model carefully against the provided images. This block is ideal for custom loops where precise component coverage is critical.
Who should skip it
Skip this option if your graphics card PCB does not match the provided compatibility images. The listing requires you to verify the model details yourself. You must also ensure your case can accommodate the 7.8-inch length. If you use 12V ARGB lighting instead of 5V, this block will not sync correctly. Users seeking a plug-and-play solution without checking compatibility should look elsewhere. Verify your specific card variant before purchasing to avoid fitment issues.
Verdict: This water block offers solid copper construction and targeted coverage for RTX 4080 cards. Verify your specific PCB layout and lighting voltage before buying.
Key specs explained
Material: Copper
Copper conducts heat faster than most other metals. This helps move thermal energy from your GPU core and memory chips into the coolant quickly. You get better temperature control during heavy loads. If you compare this to aluminum blocks, copper offers superior thermal transfer. It is the standard choice for high-performance custom loops where every degree counts.
Lighting Type: 5V ARGB RBW
This block uses 5-volt addressable RGB headers for lighting effects. RBW stands for rainbow, meaning the lights cycle through colors automatically. You need a motherboard with a 5V ARGB pin to connect it. Do not plug it into a 12V RGB header, or you will damage the LEDs. This feature adds visual flair to your build without requiring extra software control.
Dimensions: 7.8 x 5.9 x 1 inches
These physical measurements determine how the block fits in your case. The length and width must clear nearby components like VRM heatsinks or RAM sticks. The one-inch height is crucial for tube routing and clearance. Measure your specific graphics card layout before buying. If your card has bulky backplates or tall capacitors, this size might not align correctly with your hardware.
Base Plate Thickness: 10mm
A ten-millimeter thick copper base provides substantial thermal mass. This thickness helps spread heat evenly across the entire surface area. It reduces hot spots on the GPU die. Thicker plates also improve structural rigidity. When shopping, compare this to thinner alternatives. A thicker base often correlates with better heat dissipation efficiency and more durable construction for long-term loop use.
Design and Build Quality
The listing describes a second-generation three-layer structure. This design aims to increase the water flow coverage area. The manufacturer states that this layout makes water flow more scientific. The goal is to improve heat dissipation efficiency for the GPU core, VRAM, and power supply MOS. The copper plate is integrated using high-precision CNC processing. This method ensures a large water flow coverage area. The cavity undergoes rigorous fluid analysis. This process eliminates dead angles in the water flow. You get effective heat dissipation across all critical components.
The block features a 10mm thick copper plate. The listing notes that this thickness provides sufficient material for durability. The surface receives an electroplating treatment. This finish offers anti-oxidation and corrosion resistance. The thick plate allows for a single-layer sealing ring design. This approach reduces the risk of leakage compared to thin plates that require multiple rings. The copper plate also uses large area hollowing out. This technique reduces the overall weight of the cold head. A lighter unit helps protect the PCB from deformation.
The dimensions are 7.8 inches in length and 5.9 inches in width. The height is 1 inch. The height of several positioning columns is optimized. This ensures they fit required heat dissipation components strictly. The listing advises you to double-check your graphics card model. You must verify compatibility before purchasing. The unit supports 5V ARGB lighting. This adds visual customization to your build. The design prioritizes structural integrity and thermal coverage over aesthetic complexity.
Setup And Daily Use Notes
Setting up this block requires careful attention to compatibility. The listing advises you to double-check your specific graphics card model. You must compare your PCB layout against the reference images provided in the product description. This step is critical because the block fits specific board designs. The positioning columns are optimized to cover the GPU core, VRAM, and power supply MOS. If your card does not match the pictured layout, the block may not seal correctly or cover the necessary components. Installation involves connecting the 5V ARGB RBW lighting header to your motherboard. This feature allows you to synchronize the block’s illumination with other system components. The copper base plate is 10mm thick. This substantial mass helps stabilize temperatures during sustained workloads. The large area hollowing out reduces the overall weight of the cold head. This design choice protects your PCB from potential deformation under the block's pressure. The single-layer sealing ring design aims to reduce leakage risks compared to multi-ring structures. In daily use, the block relies on your loop’s flow rate and pump power. The three-layer structure directs coolant across the copper plate. This flow path is designed to eliminate dead angles. You benefit from consistent heat dissipation across the covered areas. The electroplated surface offers corrosion resistance. This ensures the block remains functional over time. The 1-inch height allows it to fit within standard case clearances. You should ensure your tubing and fittings can accommodate the block’s inlet and outlet ports. The ARGB lighting adds visual customization without requiring separate controllers. It integrates directly with your system’s lighting ecosystem. This setup process prioritizes precision fitment and electrical integration for reliable performance.
Before You Buy This Block
You need to verify compatibility before purchasing. The listing warns you to double-check your specific graphics card model. Compare your PCB layout against the reference images in the product description. This block fits specific board designs. Mismatched PCBs will not work. You must ensure the positioning columns align with your GPU core, VRAM, and power supply MOS. This product is a copper water block, not a complete cooling solution. You will need a compatible radiator, pump, tubing, and fittings to build a custom loop. The 5V ARGB lighting requires a motherboard header or controller. It does not include fans or coolant. Maintenance involves regular coolant changes and leak checks. This block suits users who already have a custom loop setup. It is not for beginners who need an all-in-one AIO. If you lack loop components, consider an AIO instead. This block is for those who want to upgrade an existing loop with a high-quality copper base. Ensure your case has enough space for the 7.8-inch length and 5.9-inch width. Proper fitment is essential for performance and safety.
Check before you buy
- Verify your graphics card model matches the PCB images
- Ensure you have a complete custom loop setup
- Check case space for the 7.8-inch length
- Confirm your motherboard supports 5V ARGB headers
