4 pure copper heat pipes wear FIN technology. The heat pipe adopts double-row staggered design, the curved part is round and thick, and the top sintering process is exquisite.Increase the fin group, maximize the heat dissipation area, double heat conduction, heat dissipation, more effective4 pin 12CM fan with temperature control , using hydraulic technology and PWM temperature control design, air volume, quiethome,office,Internet cafes, server preferred .
