## Summary description

Watercool Heatkiller V Pro GPU waterblock designed for RTX 5090 cards from Palit and Gainward. Constructed with nickel-plated copper coldplate and acrylic top in silver finish, it provides direct liquid cooling for GPU components. Includes ARGB lighting for system illumination. Intended for custom PC liquid-cooling loops to reduce GPU temperatures and noise in high-performance builds.

## Long description

The Watercool Heatkiller V Pro GPU waterblock for RTX 5090 (Palit & Gainward) is a dedicated liquid-cooling component engineered to provide direct cooling for high-performance graphics cards. Constructed with a nickel-plated copper coldplate and an acrylic top in a silver finish, this waterblock transfers heat away from the GPU, memory modules, and VRM areas into a custom loop. Integrated ARGB lighting offers customizable illumination to match system themes while the full-cover design ensures broad contact over critical components for efficient thermal dissipation.
Advantages
The nickel-plated copper coldplate delivers high thermal conductivity and corrosion resistance, while the acrylic top provides visual clarity for coolant flow and ARGB lighting effects. Full-cover contact reduces hotspot formation on GPU cores and surrounding components, enabling lower operating temperatures and reduced fan noise in the overall system. The block is designed for compatibility with Palit and Gainward RTX 5090 PCB layouts, providing a precise fit and straightforward integration into existing custom water-cooling loops.
Suitable for
Custom PC builds requiring direct liquid cooling for RTX 5090 Palit and Gainward cards
Silent or low-noise gaming rigs where reduced fan speed is desired
Overclocked systems that need improved GPU thermal headroom
Showcase PCs with ARGB lighting and visible coolant channels
Key specifications
Cooling type: full-cover GPU waterblock for liquid-cooling loops
Coldplate material: nickel-plated copper for enhanced heat transfer
Top material: acrylic in silver finish for visual aesthetics and coolant visibility
Lighting: integrated ARGB support for addressable illumination
Compatibility: designed for specific RTX 5090 PCB layouts from Palit and Gainward
Mounting: multi-point mounting compatible with target GPU models
How to use
Install the waterblock as part of a closed-loop custom liquid-cooling system following standard precautions for handling coolant and components. Remove the original air cooler and clean the GPU die, memory chips, and VRM surfaces before applying appropriate thermal interface materials. Position the waterblock over the PCB so that the coldplate makes full contact with the GPU core and other heat-producing components, then secure the block with the supplied mounting hardware. Connect inlet and outlet fittings to your loop, leak-test the system, and fill with compatible coolant. Configure ARGB lighting via the motherboard or controller according to the manufacturer’s instructions.
Usage recommendations
Use corrosion-inhibiting coolant compatible with nickel-plated copper and acrylic components, and perform a careful leak test before powering the system. Maintain periodic loop maintenance, including coolant replacement and inspection of fittings, to preserve thermal performance and visual clarity of the acrylic top.
