Cooling Location

High-heat components, such as the GPU core, memory, power MOSFETs, inductors, and tantalum capacitors.

Cooling Principle

The high-purity oxygen-free copper baseplate of the graphics card water block covers key high-heat components, including the GPU core, memory, power MOSFETs, and tantalum capacitors. The heat absorbed by the water block is then carried away by the flowing coolant.

Water Block Features

High Thermal Conductivity:

The baseplate uses T2 oxygen-free copper, with a thermal conductivity of up to 401 W/m·K, effectively improving cooling efficiency and increasing the heat dissipation area.

High-Density Jet Microchannel Design:

The water channel area is enlarged, with up to 176 microchannels, each with a groove at the bottom. The asymmetrical 5+3 channel configuration (0.5 mm slot width, 0.01 mm spacing) increases the contact area between the coolant and the base plate, thereby improving the cooling efficiency of the water block.

Full Metal Coverage:

The copper plate extends to 157 mm in length, maximizing coverage of the coolant flow area.

Lightweight Design:

Reduces the weight of the water block and prevents PCB deformation. A more reliable passivation process ensures faster heat conduction while effectively resisting corrosion and wear.
