Waterblock Alphacool for GeForce RTX 5080 / 5070 Ti – liquid cooling component (MPN 14741)

Alphacool waterblock for GeForce RTX 5080 / 5070 Ti is a dedicated liquid-cooling component designed for custom water-cooling loops in desktop gaming and workstation PCs. It replaces or supplements the stock cooling solution to provide direct heat transfer from the GPU core and surrounding components to the coolant, helping to lower operating temperatures and enable quieter system operation. The unit is intended for users who assemble or upgrade a custom loop and seek improved thermal performance and stability for high-power graphics cards.

Advantages

This Alphacool waterblock offers direct-contact cooling for the GPU, improving heat dissipation compared with air-only solutions. Its construction supports efficient coolant flow across the GPU die and nearby VRM areas, which can reduce peak temperatures and thermal throttling under sustained load. The waterblock is compatible with standard fittings used in custom loops and allows for quieter system operation by reducing reliance on high-speed fan cooling.

Suitable for

• Custom liquid-cooling loops in gaming PCs
• Workstation systems requiring sustained GPU performance
• Upgrades to reduce GPU temperatures and fan noise
• System builders and modders integrating full-coverage GPU cooling

Key specifications

• Compatibility: Designed for NVIDIA GeForce RTX 5080 and 5070 Ti graphics cards
• Cooling type: Full-coverage GPU waterblock for liquid cooling loops
• Material: Metal and transparent top (visual coolant inspection) — typical waterblock materials for thermal conductivity
• Connection type: Standard G1/4 or compatible fittings for custom loop integration
• Flow design: Engineered coolant channels for direct heat transfer from GPU and adjacent components

How to use

Install the waterblock as part of a prepared custom liquid-cooling loop following the manufacturer's mounting instructions and using appropriate thermal interface material between the GPU die and the block. Ensure the system is powered off and the graphics card is removed from the motherboard before beginning installation. Mount the waterblock to the graphics card with the supplied hardware, connect inlet and outlet fittings to the loop tubing, and perform a controlled leak test with the loop powered off. After confirming there are no leaks, fill and bleed the loop, then monitor temperatures during initial operation to verify correct installation and performance.

Usage recommendations

Use corrosion-inhibited coolant and compatible tubing and fittings. Verify clearance in the PC case and ensure sufficient radiator capacity and pump performance for the GPU's thermal load. Periodically inspect fittings and coolant condition and perform maintenance on the loop to preserve cooling efficiency and system reliability.
