Waterblock Alphacool pour GeForce RTX 5070 (référence) — WAK Core, modèle 10271

Alphacool WAK Core full-cover water block model 10271 is designed specifically for the NVIDIA GeForce RTX 5070 reference PCB. The block provides direct liquid contact to the GPU die and surrounding components, enabling efficient heat transfer from the graphics card into a custom liquid-cooling loop. Constructed to fit the reference layout, it requires compatible fittings and coolant and is intended for integration into custom water-cooling systems in gaming and workstation PCs.

Advantages

The Alphacool water block lowers GPU operating temperatures by transferring heat directly to the coolant, which reduces fan noise and allows for more stable performance under sustained load. Its full-cover design also cools nearby VRAM and VRM components, contributing to improved overall thermal management of the graphics card. The unit is compatible with standard liquid-cooling fittings and designed for leak-free integration when mounted correctly to the reference PCB.

Suitable for

• Custom water-cooling loops in gaming desktops
• Workstation PCs requiring improved GPU thermal performance
• Overclocking and sustained high-load GPU workloads
• Silent or low-noise system builds where fan reduction is desired

Key specifications

• Compatibility: NVIDIA GeForce RTX 5070 reference PCB layout
• Type: Full-cover water block for liquid cooling
• Cooling area: GPU die plus surrounding VRAM and VRM components
• Material: precision-machined cold plate and transparent top (materials as per manufacturer)
• Connection: standard G1/4 compatible fitting ports (requires separate fittings)
• Mounting: designed for reference PCB mounting points; includes mounting hardware

How to use

Before installation, ensure the graphics card is the NVIDIA GeForce RTX 5070 reference PCB. Drain and power down the system and remove the graphics card from the motherboard. Remove the original cooling solution and carefully clean thermal interfaces on the GPU die, VRAM, and VRM areas. Place thermal pads and paste as instructed by the manufacturer, then align the Alphacool water block with the card and secure it using the supplied mounting hardware. Connect inlet and outlet fittings and integrate the block into a filled and leak-tested custom loop using compatible coolant. Power on the system and monitor temperatures and leak points during initial operation.

Recommendations

Use only compatible coolant and G1/4 fittings, follow Alphacool's mounting torque and thermal interface instructions, and perform a pressure or leak test before normal operation. Regularly inspect the loop and block for deposits or leaks and replace coolant per the coolant manufacturer's schedule to maintain optimal thermal performance.
