Watercool Heatkiller V RTX 4090 Ultra Bodenplatte - Copper full-coverage GPU cold plate

Watercool Heatkiller V RTX 4090 Ultra Bodenplatte is a full-coverage copper GPU cold plate designed specifically for the Heatkiller V RTX 4090 Ultra water block. Engineered to make direct copper contact with the covered PCB area, this base plate conducts heat away from the GPU core and nearby components for integration into custom liquid-cooling loops. The plate's full-coverage form factor supports improved thermal transfer for high-performance PC builds that require efficient dissipation and stable operating temperatures.

Advantages

The copper construction offers high thermal conductivity and durable contact with the graphics card circuit board. Full-coverage design ensures consistent heat spread across the covered area, reducing hotspots on the GPU and surrounding components. The plate is compatible with the Heatkiller V RTX 4090 Ultra water block layout and intended for seamless integration into custom cooling loops, facilitating lower operating temperatures and improved thermal performance under sustained load.

Suitable for

• Custom liquid-cooled gaming and workstation PCs using NVIDIA RTX 4090 graphics cards
• High-performance overclocked GPU setups requiring improved heat dissipation
• Systems where full-coverage cold plate contact is needed to cool VRAM, VRMs and GPU die areas

Key specifications

• Material: copper full-coverage cold plate
• Form factor: full-coverage base plate designed for Heatkiller V RTX 4090 Ultra water block layout
• Contact type: direct copper contact with covered PCB regions for enhanced thermal transfer
• Intended use: integration into custom liquid-cooling loops for graphics cards
• Compatibility: designed to match the physical layout of RTX 4090 Ultra series boards covered by the Heatkiller V solution

How to use

Install the Bodenplatte as part of the Heatkiller V RTX 4090 Ultra water block assembly following the manufacturer's mounting procedure. Ensure mating surfaces on the GPU PCB and the copper plate are clean and free of debris before applying thermal interface materials where required. Mount the block and plate with the appropriate screws and spacers supplied with the water block, then connect the assembly to your custom liquid-cooling loop. Check for correct alignment and secure, even contact across the covered areas to maximise thermal transfer.

Recommendations

Use high-quality thermal interface material between the GPU die or secondary components and the copper plate where specified. Verify compatibility with your specific RTX 4090 board revision before installation and follow torque specifications to avoid PCB damage. Perform leak testing of the cooling loop after assembly and monitor temperatures during initial operation to confirm correct performance.
