## Summary description

Full-cover GPU water block Watercool Heatkiller IV designed for Radeon RX 5700 XT graphics cards. Features an acrylic top with nickel-plated copper base for heat transfer and integrated RGB lighting. Intended for custom liquid-cooling loops to lower GPU temperatures and reduce noise. Mounting aligns to the RX 5700 XT PCB layout; requires compatible fittings and coolant.

## Long description

The Watercool full-cover GPU water block Heatkiller IV for Radeon RX 5700 XT is a purpose-built cooling component for custom liquid-cooling loops. Featuring an acrylic top combined with a nickel-plated copper cold plate, this full-cover block cools the GPU, VRAM and VRM areas according to the RX 5700 XT PCB layout. Integrated RGB lighting provides visual customization while the design maintains direct coolant contact with critical heat sources to improve thermal transfer and reduce fan noise compared with air-only cooling.
Advantages
The Heatkiller IV full-cover block uses a nickel-plated copper base to ensure efficient heat conduction from the GPU die and surrounding components. The acrylic top allows for clear visibility of coolant flow and RGB lighting while maintaining a durable seal with the base. As a full-cover solution it cools multiple hotspots on the graphics card in a single assembly, simplifying installation in a custom loop and enabling lower operating temperatures and quieter system operation.
Suitable for
Custom liquid-cooling loops for Radeon RX 5700 XT graphics cards
Users seeking reduced GPU and VRM temperatures compared with air cooling
Systems where RGB lighting integration is desired
High-performance builds requiring full-cover cooling of GPU and memory components
Key specifications
Compatibility: designed for Radeon RX 5700 XT PCB layout
Top material: acrylic (transparent)
Cold plate material: nickel-plated copper
Cooling type: full-cover water block (GPU, VRAM, VRM)
Lighting: integrated RGB
Connection: requires compatible fittings and tubing for custom loop integration
How to use
Install the Heatkiller IV by removing the original cooling assembly from the Radeon RX 5700 XT, following standard electrostatic discharge precautions. Align the water block to the PCB so that the cold plate contacts the GPU die and the mounting points match the card’s layout. Use the provided screws or compatible mounting hardware to secure the block, and connect inlet and outlet fittings to your loop’s tubing. Fill the loop with an appropriate coolant and perform leak testing before powering the system. Ensure RGB headers are connected to a compatible controller or motherboard header if lighting control is required.
Usage recommendations
Use corrosion-inhibited, manufacturer-recommended coolant and compatible fittings to maintain performance and longevity. Verify board compatibility before installation and perform a thorough leak test with the system powered off. Regularly inspect seals and coolant condition, and flush the loop as recommended by your coolant manufacturer.
