Watercool Heatkiller V Pro RTX 4090 FE ARGB raffreddatore GPU ad acqua – parte superiore in acrilico, base in nichel

The Watercool Heatkiller V Pro RTX 4090 FE ARGB GPU waterblock is a full-cover liquid cooling solution made for the NVIDIA RTX 4090 Founders Edition. It combines an acrylic top with a nickel-plated metal base plate that contacts the GPU die and surrounding memory and VRM components. Designed for custom water-cooling loops, the block supports addressable RGB integration and aims to provide lower temperatures and stable thermal performance under sustained loads in gaming and workstation systems.

Advantages

The acrylic top allows visual inspection of coolant flow and ARGB lighting effects while the nickel-plated base ensures corrosion-resistant, flat contact with the GPU die and memory modules. Full-cover coverage directs coolant across all critical heat-generating areas, enabling more uniform heat extraction compared with partial blocks or air cooling. The block is compatible with standard G1/4" fittings and is intended to integrate into existing custom loops without significant modification.

Suitable for

• High-performance gaming PCs using the NVIDIA RTX 4090 Founders Edition
• Workstation builds that require sustained GPU performance and thermal stability
• Custom liquid-cooling loops with addressable RGB lighting integration
• Users replacing air cooling to reduce GPU temperatures and acoustic noise

Key specifications

• Compatibility: Full-cover for NVIDIA RTX 4090 Founders Edition
• Top material: Acrylic (transparent) with ARGB illumination
• Cold plate material: Nickel-plated metal for direct die and memory contact
• Cooling type: Full-cover waterblock for custom liquid loops
• Fittings: Standard G1/4" thread compatibility
• Lighting: Addressable RGB support for synchronized lighting systems

How to use

Install the waterblock by first removing the graphics card cooler and cleaning the GPU die and memory surfaces of old thermal materials. Mount the waterblock onto the PCB using the supplied mounting hardware and apply appropriate thermal interface material to the GPU die and memory chips as instructed by the manufacturer. Connect inlet and outlet fittings to your custom loop using compatible tubing and G1/4" fittings, then bleed and pressure-test the loop before powering the system. Ensure ARGB connector compatibility with your motherboard or controller to enable lighting control.

Recommendations

Use corrosion-inhibited coolant and follow the loop manufacturer's maintenance schedule to avoid buildup and discoloration. Tighten fittings to recommended torque levels to prevent leaks and perform a full leak test after installation. When handling the nickel-plated cold plate and acrylic top, avoid abrasive cleaners; use lint-free cloths and isopropyl alcohol for cleaning. Verify ARGB pinout and voltage before connecting to avoid lighting or controller damage.
