Bloco de água para GPU com cobertura total Watercool Heatkiller IV para Radeon RX 5700 / XT, acrílico + níquel, RGB, preto

The Watercool Heatkiller IV full-cover GPU water block for Radeon RX 5700 / XT provides direct liquid cooling to GPU, VRAM and VRM components. Constructed with a nickel-plated copper cold plate and an acrylic top, this block integrates RGB lighting and a black finish to fit visually into custom water-cooling loops for high-performance gaming and workstation systems. It replaces the air cooler, enabling lower operating temperatures and reduced fan noise under load.

Advantages

The nickel-plated copper cold plate ensures efficient heat transfer from the GPU die while the full-cover design cools adjacent memory and voltage regulation components. The acrylic top offers visual clarity for coolant flow and RGB illumination, and the black finish provides a discreet, professional appearance in builds. Integrated RGB lighting is compatible with common controller setups and adds visual customization without affecting thermal performance.

Suitable for

• Custom water-cooling loops for gaming PCs using AMD Radeon RX 5700 or RX 5700 XT graphics cards
• High-performance workstation systems requiring sustained thermal management and low acoustic output
• PC builds focused on visual aesthetics with visible coolant channels and RGB lighting

Key specifications

• Compatibility: full-cover for Radeon RX 5700 and RX 5700 XT GPUs
• Cold plate material: nickel-plated copper for improved thermal conductivity and corrosion resistance
• Top material: transparent acrylic for visibility of coolant and RGB effects
• Finish: black
• Lighting: integrated RGB illumination
• Cooling scope: GPU core, VRAM and VRM components
• Connection fittings: G1/4" standard thread (suitable for common water-cooling fittings)

How to use

To install, remove the original air cooler and prepare the graphics card surface by cleaning thermal interfaces. Mount the water block onto the PCB according to the manufacturer’s mounting plate and screw pattern, apply appropriate thermal paste to the GPU die and thermal pads to memory and VRM areas if not pre-applied, and secure the block with the supplied hardware. Connect the integrated RGB cable to a compatible header or controller. Integrate the block into a closed-loop cooling system using compatible G1/4" fittings and ensure leak testing at low pressure before full operation.

Recommendations

Use corrosion-inhibited coolant compatible with mixed-metal loops, maintain regular coolant changes, and confirm compatibility with your specific Radeon RX 5700 / XT PCB revision. Tighten fittings evenly to avoid stress on the PCB and verify RGB connection standards for controller compatibility.
