Rectangular copper GPU waterblock with matte nickel finish and visible micro-channel array

Alphacool

Alphacool GPU Waterblock Zotac RTX 5080/5070 Ti AMP Extreme INFINITYC 2 in 1 accessory

SKU CH-Z6EP-31PKD

Copper water block with 44 micro-channels and a 158.451 mm base cools Zotac RTX 5080 and 5070 Ti AMP Extreme cards

  • 33 mm micro-channels across 44 paths maximise heat absorption
  • Extended 158.451 mm copper plate broadens coolant coverage for stronger dissipation
  • Lightweight block with nickel plating guards PCB against warping and corrosion
  • 6 mm single-layer sealing ring cuts liquid-leak risk
  • 35 mm copper base lowers thermal resistance for better conductivity

Direct-Fit GPU Waterblock

The Alphacool GPU waterblock is engineered specifically for Zotac RTX 5080 and 5070 Ti AMP Extreme INFINITYC graphics cards. It replaces the stock air cooler to deliver liquid cooling directly to the GPU die and surrounding components. The block targets builders who want lower operating temperatures and quieter operation on these exact models.

Custom-Loop Integration

Installation uses an upper and lower sandwich design that secures the block around the PCB. The single-layer sealing ring and 6MM construction aim to reduce leak risk while withstanding mounting pressure. The chemically nickel-plated copper base resists corrosion inside a custom loop. The design also lightens the assembly to help protect the PCB from bending stress.

Thermal Capacity

The copper base measures 0.35 mm thick and stretches 158.451 mm in length to cover the full core area. Forty-four micro channels at 0.33 mm width increase the heat absorption surface for the coolant flow. This structure is built to handle the thermal output of the RTX 5080 and 5070 Ti AMP Extreme cards. Builders needing compatibility with other board layouts or reference designs cannot use this block.

Questions about this item

How many micro-channels carry coolant through the 158.451 mm copper plate?

The block uses 44 jet micro-channels, each 0.33 mm wide, to spread flow across the extended copper plate.

Does the single-layer sealing ring and 6 mm construction keep leak risk low during continuous operation?

Yes, the single-layer ring and 6 mm material thickness are designed to handle install pressure and reduce liquid-leak risk.

Which Zotac AMP Extreme cards does this waterblock fit?

It is made for the Zotac RTX 5080 AMP Extreme and the Zotac RTX 5070 Ti AMP Extreme INFINITYC.
