Who it fits
Good fit for
You should consider this block if you own an MSI SUPRIM X or Gaming Trio RTX 4090. It suits custom loop builders who want full PCB coverage for maximum thermal efficiency. The 6mm copper base helps dissipate heat effectively. The included Viton rubber washer ensures a secure seal against leaks. If you have a white-themed build, the white finish matches your aesthetic. The ARGB lighting allows you to sync the GPU with other Phanteks components or motherboard addressable RGB headers.
Who should skip it
Skip this option if your graphics card is not an MSI SUPRIM X or Gaming Trio RTX 4090. It is not compatible with other brands or models. You should also avoid it if you need a black or chrome finish, as this listing is for the white version only. Do not buy this if you want a smaller block, as it is a full cover measuring 10.5 inches long. It is not a complete AIO cooler, so you will need to source your own tubing and pump for a loop.
Verdict: This block offers direct PCB cooling with a 6mm copper base for the specified MSI RTX 4090 models. It is a solid choice for custom loops with compatible cards.
Key specs explained for this block
Color: White
This finish matches white GPUs and radiators. You should choose this if your build uses white components. It ensures visual consistency across your system. Black or Chrome variants exist if you prefer darker tones. The color does not affect cooling performance. It is purely aesthetic. Select this option only if the white appearance fits your case theme and other parts.
Lighting Type: Digital-RGB, ARGB
This block supports addressable RGB lighting. You can sync the LEDs with compatible motherboards or Phanteks D-RGB products. This allows you to control colors and effects via software. It is not standard RGB. You must verify your motherboard has an ARGB header. This feature adds visual flair to your water loop without impacting thermal efficiency.
Weight: 2.59 pounds
This block is relatively heavy. The mass comes from the copper base and metal construction. You should ensure your GPU bracket can support this weight. Heavy blocks reduce strain on the PCB. They also help dissipate heat due to greater thermal mass. Compare this to lighter aluminum blocks. The weight indicates robust construction but requires secure mounting in your chassis.
Base: 6mm copper
The base is six millimeters thick copper. This material conducts heat efficiently from the GPU die. A thicker base spreads heat more evenly. It improves contact with the water flow. You benefit from better temperature uniformity. Copper is standard for high-end blocks. Thinner bases may warp. This thickness suggests durability and effective heat transfer for high-power RTX 4090 cards.
Dimensions: 10.5 x 5.95 x 0.74 inches
These dimensions define the block's footprint. You must check clearance in your case. The length covers the card. The height is low, aiding airflow. Ensure your case allows space for the block and tubing. Compare these measurements with your current GPU size. Proper fitment prevents contact with other components. Accurate sizing is critical for custom loop planning and case compatibility.
Design and build quality
The listing states the block features a full water-block design that covers the entire PCB. This layout allows for direct cooling of the graphics card components. The base is constructed from 6mm copper. According to the listing, this thickness provides a higher level of heat dissipation and transfer. You get greater fin surface area with reduced flow resistance. This choice aims for outstanding cooling performance by maximizing contact while maintaining efficient water flow. The unit weighs 2.59 pounds. It measures 10.5 inches in length, 5.95 inches in width, and 0.74 inches in height. These dimensions fit the specific MSI SUPRIM X and Gaming Trio RTX 4090 models. The white finish ensures visual consistency if you build with white components. You can also choose Chrome or Black styles if you prefer darker tones. The color does not change how well the block cools. A Viton Rubber Washer is included to retain seal force and prevent leaks. This material choice helps ensure a durable and reliable connection. Digital-RGB lighting syncs with Phanteks D-RGB products or compatible motherboards. This allows you to control the ARGB effects through your system software. The design prioritizes both thermal efficiency and aesthetic integration. You should verify your motherboard has the correct header for the lighting sync. The physical size and weight indicate a robust build meant for heavy-duty use. The specific dimensions ensure it aligns perfectly with the target GPU models without interfering with surrounding parts. This block is designed for users who want comprehensive coverage and customizable lighting.
Setup and everyday use details
You must ensure this block is compatible with your specific graphics card. The listing confirms it fits MSI SUPRIM X and Gaming Trio RTX 4090 models. This compatibility is strict. You cannot install it on other RTX 4090 variants without risking damage. The physical dimensions are 10.5 inches in length, 5.95 inches in width, and 0.74 inches in height. You need to verify your case and radiator tubing can accommodate these measurements. The weight is 2.59 pounds. This adds noticeable mass to your GPU. You should support the card properly during installation to prevent stress on the motherboard slot. The block uses a Viton rubber washer. This component helps retain seal force. It is designed to prevent leaks during the filling and operation phases. You must follow the manufacturer instructions for torque and sealing to ensure safety. For lighting, the block supports Digital-RGB and ARGB. You can synchronize the lighting with other Phanteks D-RGB products. It also works with compatible motherboard Addressable RGB lighting. This allows you to match the white finish with your system theme. The block does not have its own control software. You rely on your motherboard or Phanteks hub for color changes. Everyday use involves monitoring your system temperatures. The 6mm copper base and increased fin surface area are intended to improve heat transfer. You should expect efficient cooling if the loop is properly bled and filled. The reduced flow resistance suggests the pump workload remains manageable. You do not need to adjust settings daily. The setup is a one-time process. Once installed and filled, the block operates passively. You only interact with it when changing RGB colors or performing maintenance.
Before you buy this GPU block
You need to verify your specific MSI RTX 4090 model fits this block. It only works with SUPRIM X and Gaming Trio variants. Check your card’s exact name before ordering. You must also plan your tubing routes. The block is 10.5 inches long. This length may interfere with nearby components or case walls. Ensure your radiator placement allows for this space. You will need compatible ARGB headers or controllers. The block supports digital RGB synchronization. Match your motherboard’s addressable RGB pins for lighting control. Use the included Viton rubber washers during installation. These seals prevent leaks and maintain retention force. Proper torque is essential to avoid damage. This block suits custom loop builders who want full PCB coverage. It is not an AIO solution. You still need a pump, reservoir, and radiator. The white finish matches white builds well. If you have a black build, consider the other color options. This product is a component, not a complete cooling system.
Check before you buy
- Confirm your MSI RTX 4090 is SUPRIM X or Gaming Trio
- Check case clearance for the 10.5 inch block length
