Rectangular copper and acrylic water block with black aluminium backplate, G quarter-inch ports

Bykski

Bykski Full Coverage GPU Water Block and Backplate for Inno3D RTX 3070/3070Ti

SKU CH-6CSX-76F4R

Full-coverage water block and backplate directly cools GPU, memory and VRM on compatible Inno3D RTX 3070 and 3070Ti cards

  • TypeCPU Block
  • Full-coverage cooling for GPU, memory and VRM
  • Electroplated high-purity copper block resists oxidation
  • Black anodised aluminium backplate adds rigidity
  • High-flow design supports serial or parallel loops
  • Fits Inno3D RTX 3070 and 3070Ti models

Direct GPU VRAM VRM Cooling

This full-coverage water block is built for Inno3D RTX 3070 and 3070Ti models including iCHILL X3 Twin X2 Black Gold Supreme and AX Gaming variants. It mounts directly over the GPU memory and VRM to replace the stock air cooler. The electroplated copper cold plate and acrylic top sit on the PCB while a black anodized aluminum backplate adds structural rigidity without contacting the coolant loop.

G Quarter Inch Ports High Flow Layout

G 1/4 inch threads on both top and bottom faces let builders choose parallel or serial flow paths when chaining multiple blocks. The high-flow internal channel keeps restriction low so a single pump can drive several components in series. No extra adapters or proprietary fittings are required beyond standard hard-tube or soft-tube compression fittings.

Electroplated Copper Acrylic Construction

The pure copper base transfers heat from the core memory and power phases while the electroplating resists oxidation over long-term liquid contact. Acrylic allows visual inspection of flow and dye condition. The block fits the listed reference PCB layouts only; verify the board photograph before purchase because staggered mounting holes or component heights on other 3070 designs will prevent a seal.

Questions about this item

How often should the electroplated copper cold plate and acrylic top be inspected for oxidation or micro-channel buildup?

The electroplated high-purity copper is treated to prevent oxidation; inspect annually during loop maintenance and clean acrylic with non-abrasive fluid if flow drops.

What flow-rate ceiling does the high-flow design hit before pressure drop limits multi-block serial loops?

The high-flow channel supports series configurations without a published flow ceiling; size pump head to overcome combined block restriction in your loop.

How warm does the black anodised aluminium backplate get during all-day load when it is isolated from coolant?

The backplate is not in contact with coolant so it absorbs radiant heat only; expect warm but safe surface temperatures during continuous operation.
