Bykski N-IG3090ZF-X GPU Water Block & Backplate 3090/3080 diy cooling

SKU CH-7PE4-A4EHY MPN N-IG3090ZF-X

Full-coverage water block and backplate cools GPU, memory and VRM on Colorful iGame Battle-Axe RTX 3090 or 3080 cards

  • TypeCPU Block
  • Full-coverage cooling for GPU, VRAM and VRM on Colorful iGame Battle-Axe RTX 3090 24G and RTX 3080 10G
  • Electroplated high-purity copper block resists oxidation and maintains thermal performance
  • Black anodised aluminium backplate adds rigidity without contacting coolant
  • Standard G 1/4 in. thread fittings simplify custom-loop assembly
  • SLI and CrossFire compliant for multi-GPU configurations

Precision Fit for Colorful iGame Battle-Axe

This full-coverage water block and backplate kit is engineered specifically for Colorful iGame Battle-Axe GeForce RTX 3090 and RTX 3080 graphics cards. It targets DIY liquid-cooling builders who want to replace the stock air cooler with a rigid copper and acrylic assembly. The machined cold plate contacts the GPU die, memory modules and VRM circuitry in a single piece.

Direct GPU, VRM and Memory Cooling

The electroplated high-purity copper base draws heat from the core, the 24 G or 10 G memory chips and the power delivery components simultaneously. A high-flow internal channel design supports serial or parallel plumbing through standard G 1/4 inch ports on the top and bottom faces. The black anodised aluminium backplate adds structural rigidity without contacting the coolant loop.

Requires Custom Loop Infrastructure

Installation demands a complete open-loop system: pump, reservoir, radiator, tubing and G 1/4 fittings are not included. The block occupies two expansion slots and adds measurable weight, so the case must accommodate the extra thickness and mounting clearance. Builders without existing liquid-cooling hardware or with non-reference Colorful models should verify PCB compatibility before purchase.

Questions about this item

How much GPU memory does the compatible Colorful iGame Battle-Axe RTX 3090 have?

The block fits the Colorful iGame Battle-Axe RTX 3090 with 24 GB of video memory and the RTX 3080 with 10 GB, cooling the core, memory and VRM directly.

What thread standard do the inlet and outlet ports use?

The water block is designed for standard G 1/4 inch thread fittings, allowing parallel or serial plumbing in multi-block loops.

What mounting clearance does the included backplate add?

The black anodised aluminium backplate sits behind the PCB without contacting coolant, reinforcing the card and protecting components without increasing slot thickness.
