Electroplated copper and clear acrylic full-cover GPU water block with active backplate

Bykski

Bykski Full Coverage GPU Water Block with Active Backplate for Colorful iGame Battle-Axe RTX 3090 24G

SKU CH-PP0B-CS84W

Full-coverage copper water block with active backplate cools GPU, memory and VRMs on both sides of the Colorful iGame Battle-Axe RTX 3090 24G

  • Directly cools GPU, memory and VRM on both sides
  • Electroplated high-purity copper resists oxidation for lasting performance
  • Clear acrylic top lets you inspect coolant flow visually
  • High-flow design supports multiple blocks in series
  • Active backplate included to pull heat from the rear PCB

Targeted Compatibility

This full-coverage water block and active backplate are engineered specifically for the Colorful iGame Battle-Axe RTX 3090 24G graphics card. It directly cools the GPU core, memory modules, and voltage regulators on both sides of the PCB. The kit includes the main block, an active backplate, two stop fittings, and a bridge block for series flow. Buyers with any other RTX 3090 model or different GPU brand cannot use this block.

G 1/4 Thread Interface

The block uses standard G 1/4in threaded ports for all inlet and outlet connections. A high-flow internal design permits multiple blocks to be plumbed in series without excessive restriction. Users must verify that their loop fittings, tubing, and pump reservoir combination match this thread standard and provide sufficient flow for a dual-block series configuration. Builders using proprietary quick-connect fittings or non-standard thread sizes will need adapters.

Electroplated Copper Construction

Both the primary block and the active backplate are machined from high-purity copper with an electroplated finish to resist oxidation. A clear acrylic top provides visual inspection of coolant flow and component contact. This material choice maximises thermal transfer from the GPU, memory, and VRM areas while maintaining structural rigidity. Buyers seeking a nickel-free surface or a full-metal opaque aesthetic should look elsewhere.

Questions about this item

Should I pick the active backplate version or a core-only block for my Colorful iGame Battle-Axe RTX 3090 24G?

The active backplate cools VRM components on the rear of the PCB, giving lower memory and power-phase temperatures than a core-only block.

What does the full-coverage design actually change for my RTX 3090 thermals?

It places cold plates over the GPU die, all memory modules, and VRMs on both sides of the board, so heat from every major component enters the loop directly.

Will the G 1/4in threads limit my flow rate if I run several blocks in series?

The high-flow internal channels are designed for series loops, and standard G 1/4 fittings do not become the bottleneck at typical pump pressures.
