Product information

Description

The Watercool Heatkiller V Pro liquid cooler is a full-cover GPU water-block designed specifically for RTX 5090 cards from Palit and Gainward. It combines a nickel-plated coldplate with an acrylic top in a black finish to provide direct cooling of the GPU core, memory and VRM areas. The block integrates addressable RGB (ARGB) lighting for visual system customization and is intended for use in custom water-cooling loops to reduce operating temperatures and acoustic noise in high-performance gaming and workstation builds.

Advantages

The nickel-plated coldplate offers efficient thermal transfer and long-term corrosion resistance, while the acrylic top provides a clear, durable surface for ARGB illumination. The full-cover design ensures contact with critical GPU components for uniform heat removal. Compatibility with standard fittings and a flat mounting surface simplifies installation in custom loops. The black aesthetic integrates well with a range of system designs.

Suitable for

  • High-end gaming PCs using Palit or Gainward RTX 5090 graphics cards
  • Workstations requiring sustained GPU performance under heavy loads
  • Custom water-cooling loops aiming to lower GPU temperatures and noise

Key specifications

  • Full-cover water-block for GPU core, memory and VRM
  • Nickel-plated coldplate for improved thermal conductivity and corrosion protection
  • Acrylic top with black finish and integrated ARGB lighting
  • Designed for custom liquid cooling loops with standard G1/4 fittings
  • Compatibility tailored to Palit and Gainward RTX 5090 PCB layouts

How to use

Mount the Heatkiller V Pro onto the compatible RTX 5090 PCB following the manufacturer's mounting pattern and torque specifications. Prepare and flush the custom loop with appropriate coolant, then connect the block using standard G1/4 fittings and tubing. Ensure proper sealing of all fittings and perform a leak test before powering the system. Connect the ARGB header to a compatible controller or motherboard header to enable lighting control.

Usage recommendations

Use high-quality, corrosion-inhibiting coolant and routinely inspect fittings and tubing for wear. Follow system manufacturer guidelines for mounting pressure and clearance. Periodic maintenance of the loop—flushing and replacing coolant—will help sustain cooling performance and prolong component life.
