Product information

Description

The Watercool Heatkiller V is a full-coverage GPU water block engineered for AMD Radeon RX 6800 and RX 6900 XT graphics cards. With an acetal black top and integrated ARGB lighting, this water block provides direct liquid cooling to the GPU core, memory modules and VRM area to lower operating temperatures and reduce fan noise in custom liquid-cooled systems. It is intended for users building high-performance PCs who require efficient heat transfer and a visually integrated appearance.

Advantages

The acetal black top offers a durable, low-profile aesthetic while the full-coverage design ensures contact with all critical heat-generating components. Optimized coolant channels and a high-contact base plate improve thermal conductivity and enable stable performance under sustained loads. The integrated ARGB lighting supports synchronized illumination with compatible controllers for coordinated system lighting. The block is compatible with standard liquid cooling fittings and mounting solutions for supported AMD reference PCB layouts.

Suitable for

  • Custom liquid cooling loops in desktop gaming PCs
  • Workstations requiring lower GPU temperatures for prolonged workloads
  • Silent PC builds where fan speeds are reduced by liquid cooling
  • System builds that include ARGB lighting coordination

Key specifications

  • Compatibility: AMD Radeon RX 6800 and RX 6900 XT reference PCB layouts
  • Top material: Acetal (black)
  • Lighting: Integrated ARGB illumination
  • Coverage: Full-coverage design for GPU core, memory and VRM areas
  • Cooling type: Liquid cooling, designed for custom loops
  • Mounting: Multi-point mounting for stable contact with PCB components

How to use

Install the water block following the manufacturer’s instructions for removing the original cooler and preparing the GPU. Clean the GPU die and memory contacts, apply appropriate thermal interface material to the GPU core and thermal pads to memory and VRM areas as specified, then secure the block to the PCB with the supplied mounting hardware. Connect coolant tubing to the ports using compatible fittings and integrate the block into a closed-loop cooling system. Connect the ARGB header to a compatible controller or motherboard header to enable lighting control.

Usage recommendations

Verify that your specific GPU PCB matches the supported layouts before installation. Use recommended thermal paste and pads of correct thickness to ensure optimal contact. Flush and refill the loop with compatible coolant, check for leaks after initial assembly, and monitor temperatures and lighting settings after first power-up.
