Bykski N-GV4080EOC-X Graphics Card Water Block for Gigabyte RTX 4080 16G Eagle，Full Cover With Backplate

Bykski N-GV4080EOC-X Graphics Card Water Block for Gigabyte RTX 4080 16G Eagle，Full Cover With Backplate

TL;DR: Designed for sustained workloads on the listed compatible cards. Provides direct GPU/VRAM/VRM cooling for higher overclock headroom or extended card lifespan.

This full coverage block directly cools the video card core (GPU), graphics memory (RAM), and voltage regulator modules (VRM). By directly cooling these components, you can achieve great temperatures and reach higher overclocks or extend the overall lifespan of your card by running at below-factory temperatures.

The block is constructed of high-purity copper that is nickel electroplated to prevent oxidation. A high-flow design is used to allow multiple blocks to run in series. Top and bottom ports can be used to configure parallel or serial designs in multi-block setups.
