Nickel-plated copper GPU water block with clear acrylic top and black anodized aluminium backplate

Bykski

Bykski GPU Water Block & Backplate for Galaxy/Gainward RTX 3070

SKU CH-DBEH-DRTY0

Full-coverage water block and backplate cools GPU, memory and VRM on compatible Galaxy and Gainward RTX 3070 cards

  • TypeCPU Block
  • Full GPU, RAM and VRM cooling for stable overclocks
  • Nickel-plated copper block with acrylic top for efficient heat transfer
  • Black anodised aluminium backplate adds rigidity without coolant contact
  • High-flow design supports parallel or serial multi-block loops
  • Supplied mounting hardware and thermal paste simplify installation

Compatible Galaxy and Gainward 3070 models

This full-coverage water block fits specific Galaxy GeForce RTX 3070 Metal Master, Black General, Xiaojiang and SG variants plus Gainward Dazzle Light and Star Extreme Red Lord cards. It replaces the stock air cooler on those exact boards. Enthusiasts building a custom loop for one of these GPUs use it to move heat directly from the core, memory and VRM into liquid.

Upgrade from factory air cooling

The block swaps the original heatsink and fans for a nickel-plated copper cold plate with acrylic top and a black anodised aluminium backplate. Direct contact with GPU, RAM and VRM lowers temperatures under load, which can raise overclocking headroom and extend component life. The jump is worth it when your current card throttles or runs loud in a closed case.

Fits a custom open loop

Standard G1/4 thread ports accept common fittings and tubing. The high-flow design permits series or parallel plumbing, so the block can share a loop with a CPU block or additional GPU blocks; a separate bridge may be required for multi-card spacing. Installation hardware and thermal paste are included. Builders without a pump, reservoir, radiator and coolant cannot use this part.

Questions about this item

Which graphics cards fit the Bykski full-coverage water block and backplate?

The block and backplate are compatible only with the listed Galaxy and Gainward RTX 3070 models, including Metal Master, Black General, Xiaojiang, SG, Ti SG, Dazzle Light and Star Extreme Red Lord variants.

What installation hardware is included and what step is commonly missed?

All required mounting hardware and thermal paste are supplied; the step often missed is applying fresh paste to the GPU die, memory chips and VRM pads before securing the block.

When should the thermal pads and paste be replaced on this water block?

Plan to refresh the thermal interface material whenever the block is removed for cleaning or loop maintenance, typically every twelve to eighteen months for sustained cooling performance.
