Bykski GPU Waterblock for Gigabyte RTX 3090 TI Gaming OC 24G liquid cooler

SKU CH-S61P-PB4T3

Full-cover copper block cools GPU, memory and VRMs on compatible Gigabyte RTX 3090 TI Gaming OC 24G cards, includes 14 mm rigid-tube fittings and addressable 5 V RGB lighting

  • TypeCPU Block
  • Full-cover cooling for GPU, VRAM and VRM with .5 mm micro-channels
  • Includes two nickel-plated brass fittings for 14 mm OD rigid tubing
  • 5 V 3-pin addressable RGB lighting with remote and hub supplied
  • Inlet and outlet ports rotate freely for flexible loop routing
  • High-purity copper base electroplated against oxidation for lasting performance

Compatibility and PCB Match

This waterblock fits only the Gigabyte GeForce RTX 3090 TI Gaming OC 24G graphics card. It is not a universal cooler and will not mount on any other PCB layout. Buyers must verify their board against the reference photographs before ordering. Installing it on a different card will leave core components uncovered and uncooled.

Cooling Scope and Lighting

The full-cover design cools the GPU die, memory modules and voltage-regulator area through a 0.5 mm micro-channel copper base. Integrated DC 5 V 3-pin addressable LEDs are optional and ship with a remote control and hub. Builders who need a block without lighting or who prefer a different LED ecosystem should consider other options.

Fittings and Tubing Interface

Two nickel-plated brass compression fittings for 14 mm OD rigid tubing are included in the box. The inlet and outlet ports can be rotated to suit loop routing. No other fitting sizes or tubing types are supplied, so buyers planning soft tubing or different outer diameters must source adapters separately.

Questions about this item

Which version of this waterblock matches my Gigabyte RTX 3090 TI Gaming OC 24G?

This block is built only for the Gigabyte GeForce RTX 3090 TI Gaming OC 24G; compare your card's PCB to the gallery photos before ordering.

What does the 0.5 mm micro-channel design do inside my loop?

The 0.5 mm channels increase flow velocity over the GPU, MOS and RAM zones, letting even a low-head pump move enough coolant for full-cover cooling.

What tubing standard do the included G1/4 fittings accept?

The two nickel-plated brass compression fittings are sized for 14 mm OD rigid or hard tubing.
