Zotac RTX 3060/3070 full-coverage water block

This Bykski full-coverage water block is built for Zotac GeForce RTX 3070 X-GAMING OC and Twin Edge OC graphics cards. It cools the GPU core, memory and VRM through direct contact. The block uses electroplated high-purity copper with a clear PMMA top. A matching black anodised aluminium backplate is included.

G1/4 thread fittings and serial flow design

The block accepts standard G1/4 thread fittings for hard or soft tubing. Top and bottom ports allow parallel or serial plumbing when multiple blocks are used. High-flow internal channels support several blocks in series without excessive restriction. The backplate does not contact coolant.

Compatibility limited to listed Zotac models

This block fits only the Zotac RTX 3070 X-GAMING OC 8G and Twin Edge OC variants shown in the compatibility list. Builders using Founders Edition, other partner cards or different GPU generations cannot use it. Buyers who need a block for a non-listed card must choose another solution.
