Watercool Fullcover-GPU-Wasserkühler Heatkiller IV para Radeon RX 5700 XT — parte superior em acetal com base de cobre niquelado

Watercool full-cover GPU water block Heatkiller IV for Radeon RX 5700 XT — Acetal top with nickel-plated copper base is a full-cover cooling solution designed for direct liquid cooling of the GPU die, surrounding VRAM and VRM power areas on Radeon RX 5700 XT graphics cards. The acetal top provides a durable, opaque housing while the nickel-plated copper base offers efficient thermal transfer and corrosion resistance. The block is intended for integration into custom liquid-cooling loops to achieve lower operating temperatures and quieter system operation.

Advantages

The Heatkiller IV design provides full-cover contact with the GPU, memory and voltage regulation components, enabling uniform heat removal across critical areas. Nickel plating on the copper base improves long-term surface durability and reduces the risk of galvanic corrosion when used in mixed-metal loops. The acetal top resists scratches and offers a low-profile aesthetic that fits standard mounting layouts for Radeon RX 5700 XT cards. This block supports high coolant flow while maintaining efficient heat transfer, helping to reduce fan speed requirements and overall system noise.

Suitable for

• Custom PC liquid-cooling loops built around Radeon RX 5700 XT graphics cards
• Users seeking lower GPU and VRAM temperatures for stable overclocking
• Systems where reduced fan noise and improved thermal performance are required
• Enthusiasts assembling multi-GPU or compact high-performance builds with dedicated water cooling

Key specifications

• Compatibility: Radeon RX 5700 XT full-cover layout
• Top material: acetal (opaque, durable thermoplastic)
• Base material: nickel-plated copper for heat conduction and corrosion resistance
• Cooling scope: GPU die, surrounding VRAM and VRM areas
• Connection type: standard G1/4 or other common threaded coolant ports (for integration into custom loops)
• Flow characteristics: designed for high coolant throughput with minimal restriction

How to use

Install the water block following the graphics card-specific mounting holes and alignment points, replacing the original air cooler. Clean the GPU die and contact surfaces, apply a suitable thermal interface material to the GPU and thermal pads or paste to the memory and VRM areas as required. Secure the block using the supplied screws and mounting hardware, then connect the block to the custom loop using appropriate fittings and tubing. Perform a leakage test and fill the loop with a recommended coolant, then run the pump and verify flow and temperatures before normal operation.

Recommendations

Use corrosion-inhibiting coolant and maintain proper coolant composition when mixing metals in the loop. Ensure tight, leak-free fittings and perform periodic maintenance checks on coolant quality and flow. For best thermal contact, follow manufacturer torque guidelines for mounting screws and replace any thermal interface materials when reinstalling the block.
