Cooling Position

Components with high heat generation, such as GPU cores, VRAM, power MOSFETs, inductors, and tantalum capacitors.

Heat Dissipation Principle

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

Block Features

High thermal conductivity:

Made of T2 oxygen-free copper, the base plate delivers a high thermal conductivity of 401 W/m·K, improving heat transfer efficiency and increasing heat dissipation area.

High-density jet micro-channel design:

The waterway area is enlarged with up to 176 micro-channels, each featuring a bottom groove. The asymmetric 5+3 channel configuration (0.5 mm slot width + 0.01 mm spacing) increases the contact area between the coolant and the base plate, enhancing the heat dissipation efficiency of the water block.

Full metal coverage:

The copper plate is extended to 157 mm in length to maximize coolant flow coverage.

Lightweight design:

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

Pump Features

The all-ceramic shaft sleeve extends service life, the three-phase six-stage motor ensures long-lasting power output, and the imported main control IC provides stable operation, delivering long-term reliable coolant circulation for the water cooling system.

Fan Features

The high-static-pressure penetrating heat dissipation design efficiently removes heat at a noise level of 41 dB(A), providing long-lasting and stable cooling for the water cooling system.

Speed: 3000 ± 10% RPM | Static Pressure: 5.3 mmH₂O | Airflow: 99.5 CFM | Noise: 41 dB(A)

Radiator Features

Carefully selected high-quality aluminum materials improve heat dissipation and structural durability, ensuring reliable operation in all conditions.

Tube Features

The EPDM braided tube is heat-resistant and durable, offering a long service life and stable operation under high loads. It provides a long-term, reliable heat dissipation path for water cooling systems.
