## Summary description

Alphacool ES GeForce RTX 4080 Reference 1‑Slot Design is a full‑cover GPU water block engineered for NVIDIA GeForce RTX 4080 reference cards. It provides direct liquid cooling for GPU, VRAM and VRM on a single-slot form factor, reducing temperatures and enabling compact liquid‑cooled builds. Intended for custom water‑cooling loops in desktop PCs and high‑performance compact systems.

## Long description

Alphacool ES GeForce RTX 4080 Reference 1‑Slot Design is a full‑cover GPU water block engineered specifically for NVIDIA GeForce RTX 4080 reference cards. The block provides direct liquid cooling for the GPU core, VRAM and VRM circuitry while occupying a single expansion slot, allowing integration into compact custom water‑cooling loops and small‑form‑factor high‑performance desktop systems.
Advantages
This full‑cover design cools the GPU, memory and voltage regulation components with a single block, reducing thermal resistance compared to air cooling and separate cooling solutions. The single‑slot form factor saves space in the chassis, enabling denser component layouts or more compact builds. Constructed to integrate with standard custom loop fittings and coolant, the water block supports lower operating temperatures and can contribute to reduced fan noise from system radiators and case fans.
Suitable for
 Custom liquid‑cooling loops for NVIDIA GeForce RTX 4080 reference PCB cards
 Compact high‑performance desktops and small‑form‑factor builds
 Systems where single‑slot GPU cooling is required to save expansion space
Key specifications
 Compatibility: NVIDIA GeForce RTX 4080 reference design graphics cards
 Coverage: Full‑cover cooling for GPU core, VRAM and VRM
 Form factor: Single expansion slot width
 Integration: Designed for custom liquid‑cooling loops and standard fittings
 Intended use: Desktop PC GPU liquid cooling in compact or high‑performance systems
How to use
Install the Alphacool ES water block by first removing the original cooling assembly from the RTX 4080 reference card, following standard ESD precautions. Place the water block onto the PCB so that the coldplate aligns with the GPU die, VRAM and VRM components, and secure it using the supplied mounting hardware. Connect inlet and outlet ports to your custom loop using appropriate fittings and tubing, then perform a leak test before powering the system. Ensure adequate radiator capacity and pump flow for effective heat dissipation in the chosen loop configuration.
Usage recommendations
Use only with NVIDIA GeForce RTX 4080 cards that match the reference PCB layout. Verify clearance and slot availability in the chassis prior to installation. Employ compatible coolant and maintain regular loop maintenance, including periodic leak checks, coolant replacement and radiator cleaning to preserve thermal performance and component longevity.
