Bloque de agua para GPU Watercool Heatkiller V Ultra para RTX 5090 (Palit y Gainward), ARGB, níquel + acrílico, plata

Watercool Heatkiller V Ultra is a full-cover GPU water block engineered for RTX 5090 graphics cards from Palit and Gainward. The block uses nickel-plated copper contact surfaces and an acrylic top to deliver direct liquid cooling to the GPU die, memory modules and VRM areas. Integrated ARGB lighting and a silver finish provide visual compatibility with custom PC builds while the full-cover design focuses cooling where it is most effective to lower temperatures and acoustic output in liquid-cooled systems.

Advantages

The Heatkiller V Ultra combines a nickel-plated copper cold plate for efficient heat transfer with a clear acrylic top that accommodates ARGB illumination. Full-cover cooling targets the GPU core, surrounding memory chips and VRM components to reduce hotspot temperatures and help maintain stable performance. The ARGB lighting is compatible with standard controller headers, and the nickel finish resists corrosion while providing a neutral aesthetic for system integration.

Suitable for

• Custom liquid-cooling loops for RTX 5090 cards by Palit and Gainward
• High-performance gaming and workstation PCs requiring lower GPU and VRM temperatures
• Silent PC builds where liquid cooling is used to reduce fan speeds
• Systems where ARGB lighting is desired for visual coordination

Key specifications

• Compatibility: full-cover design for specific RTX 5090 PCB layouts from Palit and Gainward
• Cold plate: nickel-plated copper for direct contact with GPU, memory and VRM
• Top material: acrylic with integrated ARGB lighting
• Finish: silver (nickel-plated surfaces and silver-coloured acrylic accents)
• Cooling type: liquid cooling, full-cover water block

How to use

Install the Heatkiller V Ultra by following the manufacturer’s mounting instructions for the compatible RTX 5090 Palit or Gainward PCB. Ensure the graphics card is powered down and removed from the system before removing the factory cooler and preparing contact surfaces. Apply an appropriate thermal interface material to the GPU die and, where required, to memory and VRM contact pads as specified. Secure the water block to the PCB using the supplied mounting hardware and connect the ARGB cable to a compatible header or controller. Integrate the block into a closed-loop custom liquid cooling system, check for leaks, and bleed the loop before powering the PC.

Recommendations

Use coolant approved for PC liquid-cooling systems and maintain regular loop servicing. Verify PCB compatibility with Palit and Gainward RTX 5090 layouts before purchase. Follow torque guidelines for mounting screws to avoid PCB damage and perform leak tests at low pump speed prior to full system operation.
