Adopt 4 composite heat pipes,Superconducting composite tube, excellent thermal conductivity and heat dissipation performance. Using reflow soldering process,Better contact, stable thermal conductivity, high heat conversion rate, and efficient heat dissipation. Using 6025 fan, IC original-components, quiet, stable, strong wind, large air volume, fast and efficient heat dissipation. The copper base is used, and the fins are electroplated with chemical nickel.Uniform thickness, resistance, wear resistance, excellent heat dissipation performance.
