GALAXY GeForce RTX 5090 D Starry LUNA OC
Product Description:
This full-coverage water block directly cools the graphics card core (GPU), memory (RAM), and voltage regulator module (VRM). By directly cooling these components, you can effectively reduce graphics card temperature, enabling higher overclocking performance, or extend the overall lifespan of the graphics card by operating it below factory settings.
The water block is made of high-purity copper and nickel-plated to prevent oxidation. Its high-flow design allows multiple water blocks to be operated in series. Top and bottom connectors can be used to configure parallel or series schemes in multi-water block configurations.
Specifications:
Main Body Material: Nickel-plated high-purity copper
Backplate Material: Black anodized aluminum (does not contact coolant)
Compatibility:
(Including but not limited to the following models)
GALAXY GeForce RTX 5090 D Starry LUNA OC
Compatibility Note: Due to different graphics card manufacturers releasing different series and potentially using different PCB layouts, this GPU water block may be incompatible with other series not mentioned. See list.
If your graphics card is not on the compatibility list, please purchase with caution.
After narrowing down your choices, please carefully review the complete PCB image to ensure compatibility. If you have any questions, please contact customer service for confirmation.
Compatibility is based only on this PCB design.

This product does not include an English instruction manual. Please refer to the installation guide in the product gallery if needed. Generally, the thermal pads should be installed on the graphics card at the position corresponding to the protruding contact point of the water block, except for the GPU core, which itself uses a thermal pad. The correct installation position of the thermal pads is shown in the middle of the product gallery images. Installing the thermal pads on other components may result in poor contact and affect heat dissipation performance.
4. We are not responsible for any damage caused during the use of this product. Please use it at your own risk.
The copper plate of the water block is machined by a CNC machine tool. Machining marks and slight unevenness on the copper plate are normal and do not affect the use of the water block. Please note this.
